Key Features

• 4" trade size back spacer for EMT and rigid conduit
• Malleable iron construction for durability
• Designed to provide spacing between conduit and structural supports
• Works with malleable iron or aluminum clamps and one‑hole straps
• Heavy‑duty casting

What this part does

The Morris 14791 back spacer creates a fixed gap between conduit or pipe and the mounting surface so conduit clamps clear beams, strut, or other supports. It is intended for use in conduit clamp assemblies for EMT and rigid conduit.

• Provides clearance to prevent conduit or fittings from contacting the support
• Used as part of a clamp assembly to stabilize and space conduit runs

Where to use it

Use this spacer when fastening conduit or pipe to structural members that require the conduit to be offset from the surface. Typical mounting locations include beams, strut, and other supports where spacing is needed to accommodate fittings or prevent contact.

• Compatible with applications using malleable iron or aluminum clamps
• Can be paired with one‑hole straps for secure attachment to supports

Basic installation

Install the spacer as part of a clamp assembly by seating the conduit in the clamp and positioning the spacer between the clamp and the support. Tighten the clamp bolt to secure the assembly so the bolt bears against the support through the spacer.

• Seat conduit in clamp before tightening
• Ensure spacer aligns with the clamp and support before final torque
