This unit is constructed with 2" x 2" x ¼" Steel Tubing. Trolleys for this system are sold seperately (as are bags). Purchase add-ons for longer length bag racks. This rack is available in one standard height, 9\ tall.
The Zebra Trolley Rack System saves floor space in the gym by mounting to wood-studded or concrete walls. Each L Bag Rack (2 poles and 1 I-Beam cross bar) comes with all the necessary hardware for mounting.
