Learn how to use the ThermBack LED Velcro Extender Strap to get a comfortable, secure fit and extend heat therapy coverage across all body types.
Quick answer
Attach the ThermBack LED Velcro Extender Strap to your ThermBack LED to add up to 64 inches of length, ensuring a snug fit and full coverage for larger body types or when wrapping around wider areas.
Why you might need the extender strap
The standard ThermBack LED strap works well for most users, but if you have a larger torso or want to wrap the pad around a broader area like your hips or shoulders, the built-in strap may feel tight. The Velcro Extender Strap adds extra length—up to 64 inches total—so you can position the heat pad exactly where you need it without compromising comfort or security.
One trade-off: the extender adds a bit of bulk at the connection point. If you're lying on a firm surface, you may feel the Velcro overlap. Placing a thin pillow or towel under the strap area solves this without reducing heat transfer.
How to attach and use the ThermBack LED Extender Strap
- 1. Detach the existing strap: Unhook the standard Velcro strap from the ThermBack LED pad. Set it aside—you can keep it as a backup or for smaller wraps. Don't throw away the original strap; you may want it for quicker setups on narrower areas.
- 2. Align the extender strap with the pad loop: Thread the loop end of the extender strap through the fabric loop on the corner of the ThermBack LED pad. Pull it until the strap lies flat against the pad edge. Make sure the Velcro side faces outward so you can adjust tension later without twisting the strap.
- 3. Secure the extender to the pad: Fold the strap back over itself and press the Velcro firmly together. Give it a gentle tug to confirm it's locked in place. A weak bond here can cause the strap to slip during use. Press along the full length of the Velcro patch.
- 4. Wrap the pad around the target area: Position the ThermBack LED on your back, shoulder, or hip. Bring the extender strap around your body and feed it through the buckle on the opposite side of the pad. If the strap is too long, fold the excess back on itself before tightening—don't let it dangle loose.
- 5. Adjust tension for a snug but comfortable fit: Pull the strap until the pad sits firmly against your skin without pinching or restricting movement. Secure the Velcro at a point that holds the pad in place during normal movement. Over-tightening can reduce blood flow and make the heat feel less comfortable. You should be able to slide two fingers under the strap.
