Description

About this product

Stabilizer foot extensions (model RA-5108) for XMARK Viper Power Racks widen the rack's base when you train outside it with safety spotter arms or other rack attachments. Each heavy-duty steel foot runs 24 in (61.0 cm) to counter forward tipping during squats, bench presses, and rack pulls.

Sold in pairs, the extensions fit the Viper's 3 × 3 in uprights and stand in for bolting the rack to the floor — no anchors required. The pair weighs 20 lb (9.1 kg). Warranty: lifetime on the mainframe, 2 years on wearables. Ships within 1 business day, parcel to your door in 3–5 days.
