Thomas Betts HS909 Pipe Conduit Strap 3.5 in Steel

Product Description

The THOMAS BETTS HS909 is a steel, zinc-plated pipe and conduit strap designed to secure 3.5-inch pipe or conduit to structural surfaces. It features two mounting holes for fastener attachment, providing a stable, code-compliant support point in electrical, plumbing, and mechanical installations. The zinc plating delivers corrosion resistance suited for indoor and light-duty exposed environments. Electricians, plumbers, and mechanical contractors install this type of strap when routing conduit or pipe runs along walls, ceilings, joists, or framing members.

This strap is appropriate for use in residential and commercial construction where 3.5-inch pipe or conduit must be supported at regular intervals per applicable codes. It is commonly installed during rough-in phases of electrical conduit runs, plumbing pipe support, and mechanical piping systems. The two-hole mounting pattern allows secure fastening to wood framing, steel studs, concrete, or strut channel using standard fasteners. Cross-reference part numbers include Minerallac HD-295 and Raco 2241.

Installation Notes

Installation is typically performed by licensed electricians or plumbers during conduit and pipe rough-in. De-energize all circuits and shut off fluid supply before working near existing systems. Fasten using hardware appropriate to the substrate material and sized to meet NEC or IPC support interval requirements for the pipe or conduit type. Do not over-torque fasteners on steel straps, which can deform the strap and reduce holding strength.
