Description

Listing is for a set of four (4) Service Caster Series #20 1-1/4" expanding stem swivel casters, two (2) with posi locking brakes, with 4" diameter by 1-1/4" wide black soft rubber wheels capable of supporting a total weight of 800 lbs. (200 lbs./caster). When searching for a reliable and durable solution to your caster needs, look no further than the Service Caster Series 20 expanding stem soft rubber wheel casters. The Series #20 features an innovative expanding stem that can easily adapt to the inside diameter of the opening, allowing for a secure fit in round or square tubes. Simply tighten the topmost knurled nut to compress the rubber for a snug fit. For added security, further compress the rubber with a wrench via the nut under the swivel raceway. Finely crafted with a bright zinc plated finish, heat-treated ball bearing raceway, and a soft rubber wheel, this versatile caster is ideal for work tables, shop projects, or any equipment with round or square tube legs. Service Caster is unsurpassed in quality, reliability, and excellent customer service. Count on us to move you forward. • These Service Caster Series #20 Soft Rubber casters offer various wheel sizes and mounting heights: 3” Wheel: 4-1/8” mounting height; 3-1/2” wheel: 4-5/8” mounting height; 4” wheel: 5-1/8” mounting height; 5” wheel: 6-1/8” mounting height. • Weight Capacity: 3": 175 lbs, 3.5" & 4": 200 lbs, and 5": 275 lbs Capacity/Caster • All casters feature an expanding stem that is 2-11/16” in length. The expanding stem comes in 10 different diameters: (3/4”, 7/8”, 1”, 1-1/8”, 1-1/4”, 1-3/8”, 1-1/2”, 1-5/8”, 1-3/4”, and 1-7/8”). Before ordering, Service Caster recommends measuring the inside diameter of your tubing- this measurement will determine the corresponding expanding stem diameter needed. Not sure how to measure or don't see the size you need? Call us or send us a message. • Brake options include a top lock brake (TLB), a total lock brake (TTL), or a posi lock brake (PLB). The top lock brake (TLB) and the posi lock brake (PLB) places a positive locking force against the wheel tread locking the wheel only. The total lock brake (TTL) also places a positive locking force against the wheel tread, but the total lock brake (TTL) simultaneously locks the wheel and the swivel for a complete stationary position.
