Our newest Spotter Arms with Nylon Resin Pad are designed to attach to your Power Cage or Squat Stand that features 2" x 2" upright poles with 1” mounting holes. Diversify your exercise equipment collection and help increase your total body strength. These are constructed with powder coated steel and feature a nylon resin pad to help protect the steel itself. It is one of the most important pieces of workout equipment for your Power Cage or Squat Rack because they are designed as a safety mechanism accessory during strength training for sports or non-competitive weightlifting. These arms act like a non-human workout partner that will keep you safe when working out alone. These are easy to attach, just find the correct height to set it up, then simply slide into the upright pole, a quarter turn down, and you are ready to get into your exercise routine. These Spotter Arms come in pairs and they provide a safe place to store Olympic style barbells between sets. NOTE: Do not slam your barbell onto the Spotter Arms because they can break and cause a malfunction. Simply set your bar down in a controlled manner. Total weight capacity 450 lbs.
