Midland Industries CPHLS-18 Hammerlock Centre Punch Clamp

Product Description

The MIDLAND INDUSTRIES CPHLS-18 is a stainless steel hammerlock centre punch clamp designed for secure band clamping in plumbing, HVAC, and industrial piping applications. Built to the CPHLS series standard, this clamp features a double-wrapped band construction that distributes clamping force evenly around the pipe circumference. The nominal pipe size is 4.5 inches, and the band width is 0.625 inches. The stainless steel material provides corrosion resistance in wet or chemically active environments. Licensed plumbers and pipefitters are the primary installers, though HVAC technicians and general contractors also use band clamps in ductwork and equipment connections.

This clamp is suited for residential and light commercial installations where a secure, tamper-resistant connection is required on nominal 4.5-inch pipe or tubing. The hammerlock closure style allows fast field installation without special tooling beyond a standard hammer or mallet. Double-wrapped band construction is common in drain, waste, and vent assemblies as well as flexible connector applications in mechanical rooms. The CPHLS-18 is appropriate for use where stainless steel hardware is specified by code or by the engineer of record.

Key Features

• Stainless steel band and hardware for corrosion resistance in wet environments
• Double-wrapped band construction for uniform clamping force distribution
• Hammerlock closure for fast field installation with minimal tooling
• 4.5-inch nominal size fits standard pipe and fitting ODs in that range
• 0.625-inch band width provides a broad seating surface on the pipe
• Low profile at 0.7 inches height to fit tight clearances

Compatibility

Designed as an OEM-style replacement or direct-install stainless steel hammerlock centre punch band clamp for nominal 4.5-inch pipe and tubing connections in plumbing and mechanical applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and local plumbing code requirements. Shut off and depressurize the line before removing any existing clamp or fitting. The hammerlock closure is set with a standard hammer or mallet - do not use power impact tools on the locking tab, as this may deform the band. Inspect the pipe bead or fitting spigot for damage before seating the clamp.
