High-Capacity Swivel Leveling Mounts with Threaded Stud

Without Cushion

With Cushion

These mounts level heavier equipment than other similarly sized swivel mounts. In addition to supporting higher capacities, the broad Acme threads adjust with fewer turns of the stud or jam nut than other threads. A ball-and-socket joint in the base swivels to keep equipment level on slightly sloped and pitted floors. For mounting versatility, you can install these mounts in either threaded holes or unthreaded through holes at the bottom of equipment.

Zinc-Yellow-Chromate-Plated Steel Base—More corrosion resistant than nickel-plated steel, these mounts are suitable for damp environments. However, they won’t hold up to chemical cleaners, high-pressure washdowns, and other harsh conditions like stainless steel can.

303 Stainless Steel Base—The choice for most wet locations, these mounts can withstand repeated washdowns without corroding. However, they won't hold up to cleaning solutions that contain harsh chemicals like 316 stainless steel can.

Rubber Cushion—A cushion under the base grips surfaces so vibrating equipment doesn't slide. It also protects floors from scrapes and gouges.
