Looking to add some extra glide to some of the accessories? The Adjustable Glider Brackets by Gorilla Playsets enable a gliding motion instead of the typical pendulum motion of the standard swing for relaxing fun! The brackets are sold in pairs and made of steel. These adjustable glider brackets can be used on any beam that measures between 3” and 4.5” wide. The Adjustable Glider Brackets pair well with Gorilla Playsets' Dual Ride Glider or the Chill 'N Swing.
