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.

Product fields [S1].
Set ratings are the total for four casters. On an uneven shop floor one caster can lift, so plan on about three quarters of the set rating as your working limit [S2].
A loaded roll-away is heavy but moves only now and then, which is the intermittent service Hamilton describes for phenolic [S3]. The hard tread rolls with little effort, is non-marking, and shrugs off oil and grease on shop floors [S3]. Heat from welding or a nearby oven is not a problem up to 250°F [S1].
Single wheels: phenolic wheels. All tool box sets: tool box caster sets.
From 3,200 lb for the 4 in set to 5,000 lb for the 8 in set, per set of four.
Yes for heavy boxes on dry shop concrete. They roll easily and resist oil and grease, but they are loud.
Four of the five sets have side lock brakes on the two swivels. One 4 in set has no brakes.
All five sets use a 4 x 4-1/2 in top plate.
