4" phenolic toolbox caster sets | 800 lb

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.

Toolbox Caster Sets

These 4 in phenolic toolbox caster sets fit shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection are rated 800 lb per caster. Wheels are 4 x 2 phenolic in swivel and rigid models. Phenolic handles dry heat, oil, and grease, but it is not made for water or washdown. Sets of 4 show the combined set rating on the title, so divide by 4 for the per caster load. Phenolic rolls easily on smooth floors and handles heat, oil, and grease. It is hard, so it is loud on rough floors. Match the 4 x 4-1/2 in plate, bolt pattern, and overall height before you order. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Read the listing for the exact wheel size, overall height, and mount shown.

Fitting it to a tool chest

Weight: size on three wheels carrying the chest, since one corner often lifts on an uneven floor [S2]. Three of these carry about 2,400 lb, so a loaded chest under that weight is covered.

Plate: the set uses a 4 x 4-1/2 in top plate. Check the bolt holes on the chest base before ordering; smaller cabinets often use a 2-3/8 x 3-5/8 in plate instead.

Rig: put the two swivels at the handle end so the chest steers from where you push.
