SIMPLE: The concept here is simple. The claws on one side dig into the plastic to provide you with "traction" and the set-screw on the other side presses the two halves back together.
TAKE IT OR LEAVE IT: If you've got a really stubborn housing on your hands, you can leave the clips in place permanently. If you just need them to keep everything nice and tight while the glue is cooling off (and hardening up) - they can be removed and re-used again too.
CONSTRUCTION: Stamped from steel and finished with black oxide, these beefy clips will not only hold strong under high pressure without bending, they won't rust or wear over time either.
ADJUSTABLE: Why not just offer the common "C" clips found on many OEM headlights? You have to have a specific length in order for them to be useful. The Compression Clips can re-seal housings as narrow as 9mm and and wide as 19mm.
