40-inch blue stretch-lock cords for bundling
The USA Progrip 689625 stretch-lock cords measure 40 inches long and 5/16 inch wide in a blue polypropylene and rubber blend. Each cord ends in a nylon scissor-lock hook that grips without a separate knot. The pack contains 25 pieces suited for securing bundled extension cords, PVC pipe, carpet rolls, cargo racks or luggage during transport or storage.
Stretch behaviour under sustained tension
When pulled to the 60-inch stretched length the rubber core extends smoothly and the scissor-lock jaws maintain their grip on the load. The polypropylene sheath resists abrasion while the rubber returns the cord to its original 40-inch length once tension is released. No tensile-strength rating is supplied, so the cords are intended for light-to-medium bundling rather than heavy lifting or dynamic shock loads.
Quick hook attachment with scissor-lock ends
Installation is a matter of looping the cord around the bundle and pressing the scissor-lock hook onto the cord body; the nylon jaws bite automatically. The only common issue is over-stretching beyond the 60-inch limit, which can permanently weaken the rubber core. Inspect the hooks for debris before each use to ensure the locking teeth engage cleanly.

Questions about this item
Does the 40 in Stretch Lock produce any noise or heat when it is stretched all day?
The polypropylene and rubber bungee operates silently and generates no heat during continuous use.
What existing hardware is needed to use the scissor-lock ends on the 40 in bungee?
Each end requires a solid anchor point such as a hook, D-ring or fixed loop to engage the nylon scissor lock.
Will the 5/16 in wide Stretch Lock work alongside older 1/4 in bungees on the same cargo rack?
Yes, the 5/16 in width fits standard rack eyelets and can be mixed with narrower cords without interference.
