Caster shims and weld plates — steel shims for fine-tuning caster mount height (uneven floors, height matching across multiple casters) and weld-on plates for adding caster mounting surfaces to equipment that doesn't have factory mounts. Standard 4 x 4-1/2 and 5-1/4 x 7-1/4 sizes. Stocked at our Mansfield, TX facility.
| Top plate pattern | Casters it fits | Hardware on this page |
|---|---|---|
| 2-3/8″ x 3-5/8″ | 3″ to 5″ light and medium duty plate casters | Weld-on pad kit, un-plated quick-change pad |
| 4″ x 4-1/2″ | 4″ to 8″ x 2″ casters to 1,500 lb: poly-on-iron, semi-steel, phenolic, kingpinless | Bolt-on pad kit, weldable quick-change dock, shims |
| 4-1/2″ x 6-1/4″ | 6″ x 3″ to 12″ x 3″ heavy duty casters to 2,500 lb | Albion quick-release caster pad |
Weld the pad. Welding across a caster's top plate burns off the zinc plating, can distort the swivel raceway, and leaves you cutting the caster off when it wears out. A weldable pad or quick-change dock takes the weld once; the caster bolts to it and comes off with four bolts on the floor.
Quick-change docks also let one set of casters move between fixtures and let a shop ship a weldment on rented casters and take them back. See the full fabrication shop caster range for the 5″ x 2″ and 6″ x 2″ casters that pair with the 4″ x 4-1/2″ pad.
Shims adjust caster mount height in 1/16, 1/8, and 1/4 inch increments. Weld plates create a flat mounting surface where one doesn't exist. Both are common in OEM and equipment retrofit work.
When a 4-caster cart has 1 corner that doesn't touch the floor, shim that caster to level the cart.
When equipment has no caster mount, weld a plate to the equipment leg and bolt the caster to the plate.
1/16, 1/8, 1/4 inch standard increments. Stack multiple for thicker adjustments.
Shims and weld plates match standard caster plate sizes — 4 x 4-1/2 most common.
