Specification Brand : Service Caster BulletPoint : Universal Steel Wire Post Shelving Caster Set | 3" Thermo Rubber Wheel | 3/8" Threaded Stem - 2 Locking & 2 Swivel BulletPoint1 : Service Caster’s Red Polyurethane on Silver Cast Iron core wheels come in four sizes – 6" x 3", 8” x 3", 10” x 3", and 12” x 3". BulletPoint2 : Weight capacity ranges from 2000 lbs. on the 6" wheel, 2500 lbs. on the 8”, 3000 lbs. on the 10”, and 3500 lbs. on the 12”. BulletPoint3 : All wheel sizes have a 3/4" axle bore and a 3-1/2" hub length. When the spanner bushing is removed, all wheel sizes can be used on a 1" axle. Please keep in mind, the hub length is the widest point of the wheel, so it is important to ensure you can accommodate this width before purchasing. BulletPoint4 : Brake options include a top lock brake (TLB), a total lock brake (TTL), or a side lock brake (SLB). The TLB places a positive locking force against the wheel tread, locking the wheel only. The SLB places a positive locking force against the wheel hub, locking the wheel only. The TTL also places a positive locking force against the wheel tread, but the TTL simultaneously locks the wheel and the swivel for a complete stationary position.
