Learn how to tie down gear with Stretch-Loc TPU straps. This step-by-step guide covers strap selection, wrapping technique, and common mistakes for bikepacking, roof racks, and camping.
Quick answer
Secure gear quickly with Stretch-Loc TPU straps by choosing the right width for your load, wrapping snugly without overstretching, and locking the buckle so the strap stays put—even on rough terrain.
Which Stretch-Loc strap width should you choose?
Stretch-Loc straps come in two widths: 12mm and 20mm. The 12mm strap (product ID 476182) is lighter and works well for small items like tent poles, sleeping pads, or a rolled jacket on a bikepacking rig. The 20mm strap (product ID 476181) offers more surface contact and is better for heavier or bulkier loads such as a SUP paddle, dry bag, or camping chair. Both use the same tough TPU material and co-molded acetal buckles, so the choice comes down to the size and weight of what you are tying down.
If you need a variety of lengths and widths for different gear, the Stretch-Loc Strap Set (product ID 476175) gives you four pieces in one package. Its integrated keeper straps hold excess material and add grip, which is especially handy when you are reusing the same strap multiple times on a trip.
Common mistakes to avoid
Overstretching the TPU strap can reduce its grip and cause it to loosen over time. Pull only until the strap is snug against the gear, not until it feels like a rubber band. Another frequent error is threading the buckle incorrectly—the strap should pass through both slots of the acetal buckle and double back on itself. If the strap slips after a few bumps, check that the buckle is fully seated and the strap is not twisted.
Step-by-step: How to tie down gear with a Stretch-Loc strap
- 1. Choose the right strap for the load: Select a 12mm strap for small, lightweight items (e.g., tent poles, rolled sleeping pad). Select a 20mm strap for heavier or bulkier loads (e.g., SUP paddle, dry bag). If you need multiple lengths, use the 4-piece Stretch-Loc Strap Set. A common mistake is using a 12mm strap for a heavy load—it can slip under vibration. Match the width to the weight.
- 2. Wrap the strap around the gear and anchor point: Loop the strap around the item and the rack, handle, or frame. Make sure the strap lies flat and is not twisted. Leave enough slack to reach the buckle. Check that the strap passes through both buckle slots before tightening. A twisted strap will not lock properly.
- 3. Pull snug—do not overstretch: Pull the free end until the strap is firm against the gear. The TPU material has natural give; you should feel resistance but not see the strap narrow significantly. Overstretching reduces grip and can cause the buckle to slip. If the strap feels like a rubber band about to snap, ease off. Snug is enough.
- 4. Lock the buckle and secure the tail: Thread the free end back through the buckle’s second slot and pull tight. The strap should double back on itself. If your strap has an integrated keeper (Stretch-Loc Strap Set), tuck the excess tail under the keeper to prevent flapping. A loose tail can catch on branches or wind. Always tuck or trim the excess.
- 5. Test the load before moving: Give the gear a firm shake or push. It should not shift more than a fraction of an inch. If it moves, re-tighten by pulling the free end again—do not add a second strap unless the load is very heavy. A strap that feels tight at rest may loosen after the first bump. Recheck after 10 minutes of riding or hiking.
