3/4" Expanding Rubber Adapter Kit

This listing is for our 3/4" Expandable Rubber Kit. This Expandable Rubber Adapter Kit is an excellent replacement for a pre-existing kit that could be worn out or a great add-on to any stem caster with a threaded stem dimension of 1/2" diameter by 2-9/16" long. These expanding kits are a great option to retrofit a caster on top of any piece of equipment or tubing. This kit is a 1-1/2" expanding diameter rubber adapter, meaning this adapter typically fits into a 3/4" leg. The most common application for this stem size would be for kitchen prep tables. All kitchen prep tables have a 3/4" inner diameter leg tubing.

Use in round or square tubing: 3/4" tubing i.d.
Expandable Range: .720" - .851"
Includes Base Washer, Plastic Spacer, Rubber Adapter, and Knurled Nut.

Frequently Asked Questions

What wheel does this caster use?+

This caster runs a Rubber wheel. Rubber absorbs shock and protects floors, and runs quietly, which suits noise-sensitive and light-to-medium duty use.

How does this caster mount to my equipment?+

This caster uses a Expanding Rubber Stem mount (3/4" stem). Stem casters press or thread into a socket - verify the stem diameter and length match your existing setup before ordering.

What floors and applications is it best for?+

The Rubber wheel performs best on rough, uneven, or outdoor surfaces such as asphalt, gravel, and cracked concrete. For non-marking or clean-environment needs, ask us about matching tread options.

How do I order, and what are the terms?+

We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
