Holdrite 287-P Strut Adapter Clamp with Isolation Pads

Product Description

The HOLDRITE 287-P is a strut adapter clamp with integrated isolation pads designed to secure copper tube size (CTS) piping to strut channel while dampening noise and vibration transfer to building structures. Compatible with pipe sizes ranging from 1 inch to 2 inch CTS, this clamp incorporates acoustic isolation pads that decouple the pipe from the strut, reducing structure-borne sound. It is suited for installation by licensed plumbers and mechanical contractors working in residential and commercial construction where noise control is a priority.

The 287-P is used in plumbing and mechanical systems where copper tubing runs along or through building framing supported by strut channel. Typical install scenarios include domestic water distribution, hydronic heating piping, and other CTS applications in multi-family residential, commercial, and mixed-use buildings where occupant comfort and acoustic performance are design requirements. The isolation pad design addresses noise complaints common in buildings with hard-piped copper systems fastened directly to structure.

Key Features

• Accepts 1 inch to 2 inch CTS pipe sizes in a single adapter clamp
• Integrated isolation pads dampen vibration and reduce airborne and structure-borne noise transmission
• Designed for attachment to standard strut channel framing
• Engineered specifically for acoustic isolation in plumbing and mechanical piping systems
• Suitable for both residential and commercial applications

Compatibility

Designed as an OEM-style strut adapter clamp for use with 1 inch to 2 inch CTS copper piping secured to standard strut channel framing in plumbing and mechanical systems.

Installation Notes

Installation should be performed by a licensed plumber or mechanical contractor in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the water system before working on any connected piping. Ensure the strut channel is properly anchored to structure before mounting clamps. Do not overtighten fasteners, as excessive clamping force can compress the isolation pads and reduce acoustic performance.
