1-1/2" Expanding Stem Casters

Caster HQ's 1-1/2" Expandable Rubber Adapters are extremely easy to install in various tubing sizes, including both Round and Square Tubing. Commercial-grade kitchen prep tables are the most common application for rubber adapter casters. Still, these casters work in many applications and tubing with a wide range of rubber adapter sizes. The rubber adapter works by expanding inside the tubing allowing the caster to fit tight into the legs or tubing on your equipment or table. We offer 8 different sizes ranging from 3/4" , 7/8", 1", 1-1/8", 1-3/16", 1-3/8", 1-1/2", and 1-3/4". These are the most common sizes for most industry-standard inner diameters in equipment tubing or table legs. The round expandable adapters also work great in square tubing legs. By expanding, they will fill all gaps for a tight fit; sometimes, you will need one size larger if going into a Square Tube. Round adapters work and expand much better than square adapters in square tubing. We do not recommend square expandable adapters and will always recommend round adapters for both round and square tubing. The Round Rubber expands more evenly in Square tubing versus a square adapter; we only offer round adapters for both Square and Round Tubing. Give it a try!
