What the DF404 Hyperextension Bench Is

The Deltech Fitness DF404 is a heavy-duty hyperextension bench built from welded steel tubing finished in black and white powder-coat paint. It targets the lower back, glutes, hamstrings and abdominals through hyper-extension and crunch movements. A 400 lb weight capacity and zinc-plated hardware make it suitable for home or light-commercial strength training.

Who This Suits and Who Should Look Elsewhere

The adjustable leg pad with seven height positions in 2" increments accommodates users of different statures, while high-density foam and sweat-resistant vinyl keep contact points comfortable and hygienic. Lifters who need integrated weight-plate storage, a dedicated glute-ham developer roller or a fold-flat frame for tight storage will not find those features on this model.

What the Bundled Hardware Changes

The self-locking pull-pin and locking knob system lets you change pad height quickly between sets without tools. Welded joints produced to American Welding Society specifications add structural rigidity so the bench remains stable under maximum load. No additional accessories or software are included beyond the bench itself.

Questions about this item

What floor space must I clear for the DF404 bench to sit stably during use?

The super-stable base is built from heavy-gauge steel tubing with a durable powder-coat finish and is rated for a 400 lb weight capacity, so it needs a level, non-slip surface that can support that load without shifting.

Will the leg-pad pull-pin still lock securely if I keep using my older Olympic-weight plates for resistance?

Yes. The self-locking pull-pin adjusts the leg pad in 2-inch increments across seven height positions, and its zinc-plated hardware is independent of any external weight you add, so older plates do not affect the locking mechanism.

How can I confirm the bench is assembled to the correct specification after putting it together?

Check that all welded joints meet American Welding Society specifications, the black-and-white powder coat shows no gaps, the leg pad clicks into each of the seven height settings, and the frame supports the rated 400 lb capacity without flex.
