All measurements indicate the wheel diameter by the tread width.

The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.

W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.

Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.

Replacing lumber cart casters

  1. Check the plate. These use a 4 x 4-1/2 in top plate.
  2. Match heights. 6 in casters stand 7-1/2 in and 8 in casters 9-1/2 in, so do not mix sizes at the same corners.
  3. Wheel only? Replacement wheels are listed for 6 and 8 in, but measure the axle and hub length first.

Related: 6 x 2 casters and wheel parts.

Lumber cart caster questions

What casters fit a lumber cart?

Most use 6 or 8 x 2 in plate casters on a 4 x 4-1/2 in plate. Measure yours to confirm.

What is the best wheel for a lumber cart?

Polyurethane on cast iron: 1,200 lb at 6 in and 1,400 lb at 8 in, and easy on floors.

Can I replace just the wheel?

Yes. 6 and 8 in replacement wheels are listed. Match the axle size and hub length.
