Holdrite 100-18 Copper-bonded Steel Bracket 20 in

Product Description

The HOLDRITE 100-18 is a copper-bonded steel bracket designed to support and position 1/2-inch copper tubing in residential and light commercial plumbing applications. The bracket measures 20 inches in length and features 5/8-inch holes on 2-inch centers, allowing consistent pipe placement along its span. It is flat-profile construction, making it well suited for in-wall and framing installations where a low-profile mount is required. Licensed plumbers and rough-in crews install this bracket during the framing stage to set copper water supply lines at the correct position before finish work begins.

The 100-18 is commonly used to position copper water supply lines for sinks, water closets, lavatories, and other plumbing fixtures. The 20-inch flat span accommodates multiple pipe positions across a single bracket, reducing the number of individual hangers or standoffs needed during rough-in. The copper-bonded steel construction helps reduce galvanic interaction between the bracket and the copper tubing it supports, which is a common concern when dissimilar metals contact copper pipe in wet environments.

Key Features

• Copper-bonded steel construction reduces galvanic corrosion risk at the contact point with copper tubing
• 20-inch flat span with 5/8-inch holes on 2-inch centers for consistent pipe layout
• Supports 1/2-inch copper tubing used in standard residential water supply rough-in
• Flat profile suits in-wall framing and stud-bay installations
• Positions copper supplies for sinks, water closets, and other fixtures at a fixed, repeatable location

Compatibility

Designed as an OEM-style pipe support bracket for 1/2-inch copper water supply tubing in residential and light commercial plumbing rough-in applications.

Installation Notes

Installation is typically performed by a licensed plumber during the rough-in phase, before wall finishes are applied. Secure the bracket to framing members using fasteners appropriate for the substrate and in compliance with local plumbing code requirements. When soldering copper connections near this bracket, heat the pipe directly rather than the bracket to avoid damaging the copper-bonded coating. Always shut off the water supply and depressurize the line before working on any connected piping.
