The End Frame Fitting is not a fun play system, but instead it facilitates the smooth running of do-it-yourself swings. It is a commercial hardware accessory. The fitting is a heavy-duty accessory that consists of entry points to create a 2-3/8-inch diameter bipod swing. The inner diameter of the legs and top rail is 2-3/8-inch. It is made out of high quality cast aluminum. The pipes of your swing are set in the End Frame Fitting with screws and an Allen wrench is used for tightening the screws. This is the solution for construction of any swing in parks, schools, or childcare centers. Request this End Frame Fitting and create your swing safely.
