These are the same casters that theater companies use, valued for their shock-absorbing properties that let them roll near silently over uneven surfaces and bits and pieces such as screws or wood scraps. Resistant to a wide variety of chemicals, they have 2" diameter neoprene wheels with a 1" wide tread. Slow-rolling precision double ball bearings allow smooth, controlled operation. Overall height installed is 2 3/4"; load capacity of 75 lb each.
Available in pin-and-socket and plate mounting styles. The pin-and-socket casters have a steel pin that seats in a 3/8" diameter, 1 1/2" deep hole. Suitable for installation in wood or plastic legs with 1/8" minimum material required around the socket base. The plate-mount casters have a 1 7/8" x 1 3/8" mounting plate; four #8 crews required (not included).
