Made of solid heavy-duty chrome plated steel, they are 20” long and weigh 2.6 lb per peg. The MB-L provides a secure post for all style resistance bands. They are easily adjustable to all holes on your Valor Fitness BD-33, BD-41, or BD-58 rack safety arms as well as the RG-19 Rig Safety Spotter Arms. Note: the MB-L is meant for use with the aforementioned Valor Fitness racks ONLY. With a 3/4” post diameter and a 2” diameter of the welded washer stop, these band pegs provide a versatile fit for many rig formations. We recommend only using band pegs/resistance bands with equipment that is weighted down, bolted, or otherwise secured to the floor.
