Gibraltar MM80163-G Leveling Mount 300 Lb 3/8-16

Product Description

The GIBRALTAR MM80163-G is a leveling mount designed to provide stable, adjustable support for equipment, machinery, and fabricated assemblies. Standing 1.5 inches high with a 3-inch base diameter, it accepts a 3/8-16 bolt thread and supports up to 300 pounds load capacity. This mount allows height and level adjustment at the base of equipment legs or frames, eliminating the need for shims or custom spacers. It is a standard component used in light industrial, HVAC equipment installations, and mechanical rooms where precise leveling is required on hard floors.

Leveling mounts like the MM80163-G are used wherever floor-mounted equipment requires fine height adjustment or vibration isolation at the base. Common applications include air handlers, condensing units on equipment pads, compressors, pump sets, and other mechanical equipment mounted on concrete or steel surfaces. The 3/8-16 thread is one of the most common bolt thread sizes in light industrial and HVAC applications, making this mount widely compatible with standard equipment leg hardware.

Key Features

• 300 pound load capacity per mount for stable equipment support
• 3/8-16 bolt thread fits standard equipment leg bolts and threaded inserts
• 3-inch base diameter provides a broad footprint for floor contact stability
• 1.5-inch installed height accommodates typical leveling clearance requirements
• Compact, single-piece construction suited for tight equipment base clearances

Compatibility

Designed as a standard replacement or new-installation leveling mount for equipment with 3/8-16 threaded leg hardware requiring up to 300 pounds per mount capacity.

Installation Notes

Leveling mounts are typically installed by HVAC technicians, millwrights, or plumbers during equipment setting. Thread the mount onto the equipment leg bolt and adjust height before tightening the locking mechanism to secure the final level position. Ensure the floor surface is clean and free of debris before seating the base to prevent uneven loading. Always verify total load is distributed across all mounts and does not exceed the rated capacity of any single mount.
