S-5! CanDuit 1-1/4" Metal Roof Conduit & Pipe Mounting Clamp

Corrosion-Resistant Conduit Support with EPDM Protection for Metal Roofs

1-1/4" Nominal Trade Size | 1.54–1.81" Actual OD Range | M8 Mounting Stud | 10-Year Warranty
The S-5! CanDuit 1-1/4" Pipe Clamp provides a secure, organized way to mount electrical conduit, piping, and other round components to metal roofs. Designed for use with compatible S-5! standing seam clamps, exposed-fastened roof brackets, and the GRipperFix utility mounting system, CanDuit helps support rooftop conduit runs without relying on loose blocks, pads, or improvised supports.

Featuring a corrosion-resistant electro-zinc-coated steel strap, protective EPDM liner, and integrated M8 threaded mounting shaft, CanDuit is engineered for long-term rooftop applications in residential, commercial, and solar installations.

Product Highlights

• Preassembled clamp: Simplifies field installation.
• 10-year warranty: Manufacturer coverage against manufacturing defects.

Secure Rooftop Conduit Without Improvised Supports

Electrical conduit and piping installed on metal roofs require reliable support to maintain proper routing and reduce unnecessary contact with roofing surfaces.

Traditional installation methods sometimes rely on wood blocks, rubber pads, or loose supports that can trap moisture, shift over time, or contribute to unwanted roof contact.

The S-5! CanDuit system provides a purpose-built alternative that attaches conduit and piping to compatible metal roof mounting hardware.

Benefits of CanDuit Conduit Support

• Creates organized rooftop conduit runs.
• Helps keep conduit and piping elevated from the roofing surface.
• Reduces direct abrasion against roof panels.
• Supports secure attachment through compatible S-5! mounting hardware.
• Eliminates the need for improvised conduit supports.
• Provides flexible conduit routing around rooftop equipment.

Designed for 1-1/4" Nominal Conduit

The CanDuit 1-1/4" clamp is designed for conduit and piping with an actual outside diameter between 1.54 and 1.81 inches (40–46mm).

The adjustable strap accommodates slight differences in conduit and pipe diameter within this range.

Size Specifications

• Nominal trade size: 1-1/4"
• CanDuit size: #4
• Minimum supported outside diameter: 1.54" / 40mm
• Maximum supported outside diameter: 1.81" / 46mm

CanDuit sizing is based on the actual outside diameter of the conduit or pipe, not its nominal trade size alone.

Corrosion-Resistant Steel with Protective EPDM Liner

The S-5! CanDuit clamp uses an electro-zinc-coated steel strap designed to resist corrosion in rooftop environments.

An integrated EPDM liner provides a protective interface between the clamp and the supported conduit or pipe.

Construction Features

• Steel strap: Electro-zinc-coated for corrosion resistance.
• Coating thickness: Minimum 8 microns.
• EPDM liner: Helps prevent abrasion and direct metal-to-metal contact.
• Adjustable securement: Holds compatible round components within the specified diameter range.
• Integrated mounting stud: M8 threaded shaft.

Compatible with S-5! Metal Roof Mounting Systems

CanDuit is designed to work with S-5!'s metal roof attachment products, providing flexibility across multiple roofing profiles.

Compatible Mounting Options

• S-5! standing seam clamps: Non-penetrating attachment options for compatible standing seam profiles.
• S-5! Mini clamps: Compatible configurations for appropriate lighter-duty applications.
• S-5! roof brackets: Weatherproofed mounting options for exposed-fastened metal roofing.
• GRipperFix utility mounting system: Supports grouped conduit runs and other utility attachments.

The CanDuit clamp attaches through its integrated M8 threaded shaft. The supporting S-5! clamp, bracket, or GRipperFix assembly is selected separately based on the roof profile and installation requirements.

Flexible Conduit Routing and Orientation

CanDuit provides installation flexibility for rooftop electrical and mechanical systems.

Depending on the supporting mounting hardware, conduit and piping can be routed in multiple directions relative to the roof seams.

Supported Orientations

• Parallel to roof seams.
• Transverse to roof seams.
• Angled or offset relative to roof seams.
• Grouped utility runs using compatible GRipperFix hardware.

Ideal for Solar and Rooftop Utility Installations

The CanDuit 1-1/4" clamp is well suited for projects requiring organized conduit and piping support on metal roofing.

Common Applications

• Solar PV electrical conduit runs.
• Commercial rooftop electrical raceways.
• Residential solar conduit routing.
• HVAC and condensate lines.
• Compatible plumbing and utility piping.
• Rooftop equipment connections.
• Standing seam metal roof installations.
• Exposed-fastened metal roof installations.
• Grouped conduit supports using GRipperFix.

Installation Overview

The CanDuit clamp arrives preassembled and installs using compatible S-5! mounting hardware.

1. Select the roof attachment: Choose an appropriate S-5! clamp or bracket for the roof profile.
2. Install the mounting hardware: Secure the roof attachment according to its manufacturer instructions.
3. Attach CanDuit: Thread the integrated M8 mounting shaft into the S-5! attachment.
4. Open the strap: Remove one of the upper clamp screws.
5. Position the conduit: Place compatible conduit or piping inside the EPDM-lined clamp.
6. Secure the strap: Reinstall and tighten the screw to hold the conduit in place.

For GRipperFix installations, an additional M8 flange nut is required.
