S-5 CanDuit is a pipe and conduit securement clamp designed to support round objects on metal roofs while helping protect the roof surface from abrasion, corrosion, and unnecessary damage. It can be used to secure conduit, piping, condensate lines, gas piping, and other round shapes in residential and commercial applications.
Instead of relying on makeshift supports such as wood blocks, concrete blocks, rubber pads, or other materials placed directly on the roof, CanDuit provides a purpose-designed method for organizing and securing rooftop piping and conduit. S-5! states that CanDuit can be paired with its non-penetrating clamps for standing seam roofs, weatherproofed brackets for exposed-fastened roofs, and the GRipperFix utility system.

Why Proper Pipe and Conduit Securement Matters on Metal Roofs
Rooftop conduit and piping are common on commercial and industrial buildings. Electrical conduit, condensate lines, gas piping, and other mechanical services may need to travel across the roof to connect different areas of a facility.
The challenge is securing these components without creating unnecessary problems for the roof.
Improvised supports can trap moisture against the metal panel, create abrasion points, interfere with drainage, or introduce materials that may contribute to corrosion. S-5! specifically warns against using makeshift assemblies such as wood blocks, concrete blocks, rubber pads, and Unistrut directly on the roof because they can trap moisture, cause corrosion, and potentially affect the roof warranty.
The S-5 CanDuit system provides a dedicated attachment point for round objects while keeping the installation organized.
For metal roofing applications, that distinction matters. A rooftop accessory should not simply hold a pipe in place; it should also be selected with the roof profile, attachment method, load requirements, and weather exposure in mind.
How S-5 CanDuit Works
The CanDuit clamp wraps around a round pipe, conduit, or similar object and uses an integrated threaded connection to attach it to a compatible S-5! clamp or bracket.
The design allows the supported object to be positioned relative to the roof seam rather than forcing every installation into one orientation.
According to S-5!, CanDuit can mount round shapes parallel, transverse, or at an angle to roof seams. The M8 threaded shaft mounts directly to compatible S-5! clamps and brackets.
This creates a modular attachment system:
Metal roof → S-5! clamp or bracket → CanDuit → pipe or conduit
The specific roof attachment component depends on the roof profile and substrate. A standing seam roof may use a non-penetrating seam clamp, while exposed-fastened or corrugated systems may require a compatible bracket.
That means CanDuit should not be selected independently from the roof attachment method. The complete assembly needs to be compatible with the existing roof system.
Key Features of S-5 CanDuit
14 Available Sizes
CanDuit is available in 14 sizes covering round-object outside diameters from approximately 0.79 inches to 4.6 inches.
This range allows the product to accommodate many common conduit and piping sizes. S-5! recommends matching the clamp’s adjustment range to the outside diameter of the pipe or conduit rather than selecting solely based on nominal pipe size.
Corrosion-Resistant Steel Strap
The CanDuit strap is made from electro-zinc-coated steel. S-5! specifies a minimum coating thickness of 8 microns for the product.
The coating is intended to provide corrosion resistance for rooftop applications where the component is exposed to changing environmental conditions.
EPDM Liner Pad
The interior of the clamp includes an EPDM liner pad.
The liner helps prevent abrasion between the clamp and the supported pipe or conduit. This is particularly important where the supported component could otherwise rub against a metal clamp during vibration or movement.
M8 Threaded Shaft
The M8 threaded shaft provides the connection point between CanDuit and compatible S-5! clamps or brackets.
This makes the product part of a broader modular rooftop attachment system rather than a standalone pipe support.
Flexible Orientation
CanDuit can be positioned to support round objects parallel, transverse, or at an angle to roof seams. This provides additional flexibility when routing conduit and piping across complex rooftop layouts.
10-Year Manufacturing Warranty
S-5! states that CanDuit carries a 10-year warranty against manufacturing defects. Warranty terms and conditions should be reviewed before specifying the product for a project.
What Can S-5 CanDuit Secure?
CanDuit is designed for a range of rooftop round objects.
Common applications include:
- Electrical conduit
- Condensate lines
- Gas piping
- Mechanical piping
- Utility piping
- Other round rooftop components
The product has been used in commercial applications where significant lengths of rooftop conduit and piping need to be supported without creating numerous roof penetrations. In one S-5! case study, the Ray Miller Community Center used CanDuit clamps and GRipperFix to secure approximately 600 feet of rooftop conduit and piping.
The same project used a standing seam metal roof to provide a platform for future solar installation while keeping the rooftop mechanical attachments penetration-free.
This illustrates an important advantage of planning rooftop attachments as part of the overall roof design rather than treating conduit and piping as an afterthought.
Can S-5 CanDuit Be Used on Different Metal Roof Types?
CanDuit is designed to work across multiple metal roof configurations when paired with the correct S-5! attachment product.
S-5! identifies compatibility with:
- Standing seam metal roofs
- Exposed-fastened metal roofs
- Corrugated metal roofs
The CanDuit itself secures the round object, while the appropriate S-5! clamp or bracket provides the connection to the roof.
This distinction is important because metal roof profiles vary considerably.
A clamp designed for a standing seam roof should not automatically be assumed to work on an exposed-fastened or corrugated roof. The attachment component must be selected for the actual roof profile and substrate.
Before ordering, identify the roof type and confirm the appropriate S-5! attachment method.
CanDuit With S-5! Clamps and GRipperFix
One of the strengths of CanDuit is its ability to work as part of a larger rooftop utility attachment system.
S-5! Clamps
For standing seam applications, CanDuit can be paired with compatible S-5! clamps that attach to the seam without requiring a traditional roof penetration.
This can be useful when rooftop conduit needs to be installed while preserving the integrity of the standing seam roof system.
S-5! Brackets
For exposed-fastened and other metal roof profiles, compatible S-5! brackets can provide the attachment point for CanDuit.
The appropriate bracket depends on the roof profile and attachment conditions.
GRipperFix
GRipperFix can be used with CanDuit to organize multiple pipes or conduits into groupings or support a single pipe between two seams. S-5! identifies GRipperFix as a utility support system that can work with CanDuit for these applications.
This can be particularly useful on commercial rooftops where multiple utility lines need to follow a coordinated route.
CanDuit vs. Improvised Rooftop Pipe Supports
Improvised rooftop supports may appear inexpensive, but they can create problems over time.
| Factor | S-5 CanDuit | Improvised Supports |
|---|---|---|
| Purpose-designed for rooftop piping | Yes | No |
| Pipe/conduit protection | EPDM liner | Varies |
| Organized attachment | Yes | Often inconsistent |
| Roof compatibility | Designed for metal roof attachment systems | Depends on method |
| Corrosion considerations | Corrosion-resistant clamp construction | Varies |
| Multiple pipe organization | Can pair with GRipperFix | Often difficult |
| Roof penetration required | Depends on attachment system; non-penetrating options available | Varies |
| Manufacturer-supported product | Yes | No |
The goal is not simply to prevent a pipe from moving. The attachment method should also consider the roof surface, drainage, corrosion, abrasion, wind loads, and the long-term condition of the building envelope.
Selecting the Correct CanDuit Size
Choosing the correct CanDuit size starts with measuring the outside diameter of the object being supported.
The product is available in 14 size ranges, from approximately 0.79–0.94 inches on the smallest size to 4.25–4.6 inches on the largest.
A simplified selection table is:
| CanDuit Size | Approximate Outside Diameter Range |
|---|---|
| #1 | 0.79–0.94 in. |
| #2 | 0.98–1.18 in. |
| #3 | 1.26–1.46 in. |
| #4 | 1.54–1.81 in. |
| #5 | 1.89–2.10 in. |
| #6 | 2.10–2.32 in. |
| #7 | 2.30–2.60 in. |
| #8 | 2.64–3.00 in. |
| #9 | 2.90–3.15 in. |
| #10 | 3.27–3.67 in. |
| #11 | 3.40–3.70 in. |
| #12 | 3.70–4.10 in. |
| #13 | 4.00–4.37 in. |
| #14 | 4.25–4.60 in. |
These are published adjustment ranges, not a substitute for project-specific engineering or installation requirements. Always verify the actual outside diameter and selected attachment assembly before installation.
Installation Considerations for Metal Building Roofs
A CanDuit installation should be treated as part of the complete roof attachment system.
Before installation, identify:
- Metal roof profile
- Standing seam or exposed-fastened configuration
- Roof panel material
- Pipe or conduit outside diameter
- Required attachment locations
- Supported load
- Wind exposure
- Pipe movement
- Thermal expansion requirements
- Drainage paths
- Compatible S-5! clamp or bracket
The roof itself also needs to be structurally adequate for the loads being introduced.
S-5! notes that loads imposed on its clamps are transferred to the roof panels and ultimately into the building structure. The adequacy of the roof panels, panel attachments, and building structure therefore needs to be verified for the specific application.
For projects with significant rooftop utility loads, a qualified design professional should evaluate the attachment spacing and structural requirements.
Things to Know
- Measure the actual outside diameter. CanDuit sizes are based on adjustment ranges, so verify the diameter of the pipe or conduit before selecting a clamp.
- Identify the roof profile. Standing seam, exposed-fastened, and corrugated roofs require different attachment approaches.
- Choose the correct S-5! attachment component. CanDuit is the pipe/conduit clamp; the roof connection is made through a compatible clamp, bracket, or utility system.
- Avoid improvised supports. Materials placed directly on the roof can trap moisture, cause abrasion, and contribute to corrosion.
- Protect the supported pipe. The EPDM liner helps prevent abrasion between the clamp and the supported object.
- Consider wind and structural loads. The complete attachment assembly needs to be appropriate for the roof and building structure.
- Plan conduit routes carefully. CanDuit allows round objects to be positioned parallel, transverse, or at an angle to roof seams.
- Consider GRipperFix for multiple lines. Grouping multiple conduits can create a cleaner and more organized rooftop installation.
- Follow the manufacturer’s installation requirements. Product-specific instructions should take precedence over generic installation practices.
