Bare Steel Equipment Stubby Stack Weight Pin

These pins rely on powerful magnets to secure themselves, so they require a ferrous metal surface to function. They will not stick to rubber-coated, urethane, or plastic-encased weights.

Yes, the magnets are designed to hold firm against the vibration and movement of standard cable stack exercises. However, they are not intended for high-impact movements where the weight stack might slam or bounce aggressively.

You can, provided there is enough surface area for the magnets to make full contact. Just ensure the pins are centered and flush against the metal to maintain a secure hold.

They are specifically compatible with PowerBlock-style dumbbells that feature exposed metal plates. If your adjustable dumbbells are fully enclosed in a plastic shell, these pins will not be able to attach.

The bare steel is durable, but it can develop surface rust if exposed to moisture or extreme humidity. We recommend wiping them down after sweaty workouts and storing them in a dry environment.
