How delivery works
Your item’s shipping method and price are confirmed in the shipping calculator and at checkout. Here is what each delivery path means.
Driveway freight delivery
Your equipment is palletized and protected. The freight carrier schedules delivery, then uses a liftgate to lower it to your curb or driveway. Moving it inside and unpacking it are up to you.
Inside delivery & assembly
When selected and available for your address, the delivery team brings the equipment into the room, assembles and tests it, then removes the packaging.
Full truckload
For commercial builds and multi-pallet orders, a dedicated trailer keeps the full order together in one delivery. We confirm the unloading plan before the truck ships.

Check your purchasing powerWhat Remanufactured Means
Every remanufactured machine is fully disassembled, deep cleaned, repaired or re-parted to factory spec, then tested under load before it ships. Backed by one year parts and labor, with extended coverage available.
Warranty Coverage
New and remanufactured equipment are both covered for one year, parts and labor, backed by us. Extended protection is available on either through BAG Care+. Used equipment is sold as-is with no warranty coverage, and is described honestly before you buy. We service nationwide - every ZIP code in the country - so coverage travels with the machine.
30-Day Returns & Exchanges
Change your mind within 30 days of delivery and you can return the machine or exchange it for a different size, color or configuration.
Return shipping is the customer's responsibility and a 15% restocking fee applies to preference returns and exchanges. Freight items must go back packaged to the same standard they arrived in — we will tell you exactly what that means before anything is collected.
Anything that arrives damaged or fails under warranty is handled separately and carries no restocking fee. Full terms are in our Returns, Exchange & Refund Policy.

Commercial-grade equipment, inspected and supported by warranty.
The Hammer Strength Select Leg Extension delivers controlled quadriceps isolation with all adjustments accessible from the seated position, a five-position start mechanism, and a roller-based seat adjustment — the five-position adjustable start sets the lower leg pad position relative to each user's shin length before the extension begins, which aligns the machine's rotation axis with the knee joint. Correct axis alignment ensures consistent quad loading through the full extension arc and reduces anterior knee shear forces at the bottom of the movement. All adjustments are made from the seated position, eliminating the need to stand, reposition, and remount between setup changes.
Roller seat mechanism for fast sizing between users. 295 lb selectorized stack on a 570 lb commercial frame, 47" × 41" footprint, 300 lb max user. Remanufactured.
