Frequently Asked Questions
How does an expanding adapter work? ›
A rubber plug with a bolt through the center expands when tightened, creating a secure friction fit inside the tube. Tighten the nut and the caster is installed.
Is the 3/4-inch measurement the inside or outside diameter? ›
It is the inside diameter (ID) of the tube. Measure the inside opening of your tube leg to confirm it is 3/4 inch.
Can expanding adapters support heavy loads? ›
Expanding adapters are designed for light to medium-duty applications. Check individual product load ratings for specific capacity.
