The Secret to Installing a Locking StripAdmin
One of the better innovations in weatherstripping of the 1970’s is the locking strip. Anything to make the job of installing glass into a vehicle easier was a welcome change in the automotive industry.
A locking strip is simply that- a small, narrow strip of rubber that inserts into a groove in a gasket, locking the gasket tight around the glass. Sounds simple enough, right? Well the concept is, yes. But the installation can be tricky.
When I say these things lock in tight, I mean TIGHT. You’re pushing rubber into rubber into a very tight space and it can be hard and frustrating. That’s why we’ve gathered up these helpful tips to take the frustration away and help you do it right the first time…. And without losing your mind.
Tip 1: Lubricate. We suggest plain old regular dish soap and water. Its slippery, non-toxic and evaporates away over time. Apply it liberally to the locking strip and in the groove in the gasket itself and it should slide right in.
Tip 2: Start in the right location. Start in the bottom middle of the glass you’re working on and work your way around to the other side.
Tip 3: Cut the locking strip a little long. When you get to the end of your installation and it’s time to trim off the length at the end, trim it a half inch or so too long. Install the very end into the groove, right up against the starting end and then work the extra back into the gasket. This will prevent any kind of gap in the locking strip now and in the future in the case of any shrinkage.
Tip 4: Use a locking strip tool. These specialty tools are affordable and great to aid in this process. You insert the locking strip through the small hole in the tool. Then you run the tool through the groove in the gasket. It holds the groove open while feeding the locking strip down into it. It still requires some lubrication and elbow grease on your part but makes a much easier time of the job. We sell 2 different types:
