Frequently Asked Questions
How do I know which attachments will fit my power rack?
Measure the cross-section of your uprights (common sizes are 2" x 2" and 3" x 3") and the hole diameter and spacing. Check the attachment’s fit notes—many listings specify compatible models or tube sizes. If the listing lacks specifics, contact the seller or manufacturer before buying.
Are spotting arms safer than J-hooks?
Spotting arms are designed to catch a dropped bar and are generally safer for movements that risk forward drop (e.g., box squats). J-hooks are excellent for racking but offer less protection for failed lifts. Choose based on the lifts you perform and add both types if space and budget allow.
What should I do if parts are missing or the attachment feels wobbly?
First, double-check the included parts list and hardware. Tighten all fasteners and verify you used the correct holes and pin positions. If something is missing, contact the seller promptly for replacement parts. For wobble, ensure upright compatibility and consider adding floor anchors or anti-tilt hardware if the rack supports it.
