Sold as a Pair
20 inch arms, 16 lb each
5/8 Inch Pin
Profile PRO, sold after 8/29/2023
A pair of 20 inch spotter arms that bolt to the front of your Profile PRO and catch the bar when a rep goes wrong. The pair is rated to 1,000 lb, and UHMW strips along the top keep steel off your knurling. They pull double duty for rack pulls, rows and overhead pressing too.
Genuine PRx Performance
Synergy Custom Fitness is a PRx Performance retail partner. These are the same spotter arms PRx sells directly, fulfilled and shipped to your door by PRx itself.
Check your rack first. These arms fit 3x3 Profile PRO racks sold after August 29, 2023, on 5/8 inch pins. Synergy racks and uprights use 1 inch holes, so this attachment is not made for them. It is built for PRx uprights with 5/8 inch holes..
Lift Without a Partner
Set the arms just below the bottom of your range and a missed squat or bench rep lands on steel instead of on you. Train heavy alone with a real safety net.
Saves Your Knurling
UHMW wear strips line the top of each arm, so a dropped or racked bar meets plastic instead of bare steel and the knurling on your barbell stays sharp.
More Than Safety
Use the arms as a working surface for rack pulls, bent over rows and standing overhead press, setting the bar at exactly the height each lift starts from.
Rated to 1,000 lb
Each 20 inch arm is 3x3 steel in black powder coat, and the pair carries a 1,000 lb capacity, so the catch is stronger than any rep you will miss.
Made for the Profile PRO
Built for 3x3 Profile PRO racks sold after August 29, 2023, on 5/8 inch pins. Attach them to the front of the rack after you unfold it.
Not for Synergy Racks
Synergy uprights use 1 inch holes, so these arms are not made for them. Check that your rack is a Profile PRO with 5/8 inch holes before you order.
