These spreader bars are a solid wood rod(1 3/8" dia) tightly carefully and tightly wrapped with durable industrial black rubber. The rubber cap on each end and a heavy duty long shank eyebolt screwed into the wood for for the most secure hold you can hope for! They include a center rope 'groove' to attach a rope without it sliding back and forth on the bar. We make a 24" and a 36" bar.
These Spreader Bars are a great addition to any collection or dungeon. (Heavy duty but not designed for suspension play.)
