About Leveling Mounts

Choose the right leveling mounts for your floor conditions, equipment weight, and vibration-control needs.

Heavy Duty Rigid Leveling Mounts


Grooved Surface	Smooth Surface

The highest capacity mounts we offer, these support up to 110,000 lbs. to level heavy machinery. Rest large equipment, such as CNC and injection molding machines, on top of these mounts and the weight will keep them in place. Turn the hex head bolt with a wrench to adjust the height and angle.

Iron Base and Painted Steel Base—These mounts are best for dry environments since moisture will cause them to rust.

Vibration-Damping Heavy Duty Rigid Leveling Mounts

Grooved Surface

The highest capacity vibration-damping mounts we offer. The rubber or felt cushion reduces vibration to protect components and extend your machine’s life. Rest large equipment, such as CNC and injection molding machines, on top of these mounts and the weight will keep them in place. Turn the hex head bolt with a wrench to adjust the height and angle.

Iron Base—These mounts are best for dry environments since moisture will cause them to rust.

Rubber Cushion—In addition to reducing vibration, the cushion grips surfaces so vibrating equipment doesn't slide. It also cuts down on noise and protects floors from scrapes and gouges.

Heavy Duty Tapered Shims

Image of Product. Front orientation. Contains Annotated. Shims. Sold Individually, Heavy Duty, Taper.

Align heavy machinery. Originally designed for leveling leaf springs on pick-up trucks, these aluminum shims are stronger than plastic and wood shims. Wedge them under your machine’s feet until you reach the desired level—no need to stack multiple flat shims. Ridges grip surfaces to prevent these shims from sliding, while also facilitating small adjustments. To secure them in place, drive a screw through the center mounting hole.

Tapered Shims

Wedge these angled shims into gaps to quickly level cabinets, doors, and windows without stacking multiple flat shims.

Wood

Made of kiln-dried wood, these smooth shims resist molding and rotting. All are hand sorted for quality but may split when nailed or screwed. Easily snap off any excess to get the length you need.

Composite

More durable than traditional wood shims, these are less likely to split when nailed or screwed. They will not mold or rot. All are scored to easily snap off any excess to get the length you need.

Plastic

These shims won't degrade when exposed to moisture or chemicals. They're also naturally mold and rot resistant. All are ribbed to grip surfaces and keep these shims from sliding, while also facilitating small adjustments. Trim any excess with a utility knife to get the length you need.

Flexible—These shims conform to uneven surfaces but are not as precise as rigid shims. They're also easier to trim.

Rigid—These durable shims maintain their shape, so they're more precise than flexible shims.
