Securing gasket strip to a metal back box.

[Bill]

Following on from a phone call I had earlier this week I thought that I had better try this.

We were talking about the problem of securely gluing a strip of flexible gasket into a metal back box.

I suggested "Gorilla Glue", which is a low expansion foam and sticks like $hit to the proverbial blanket. Having suggested it I thought that I'd better try it. Just a very thin line of it inside the strip plus a bit of moisture, an hour or so wait and it is well and truly stuck. Nothing short of an angle grinder will move it!

Apart from the time delay it seems quite promising.

Does any one else have a favourite gluing method?

Evostik?

[Bill]

Maybe, it needs to be quite firm and not give way if long lengths cables are pulled through the aperture.

I've used Evostick in the past. Need to make sure solvent is completely gone before operating any nearby switches, particularly if you've used it on something like a steel consumer unit - I let it fully set for a couple of days before installing.

BTW, a good way of making your own grommet strip is to slice down the centre of T&E (knife against the earth), and use the resulting discarded sheath. You get a slightly wider and slightly narrower side given the knife is one side of the earth, and you can get different thicknesses by using different thickness T&E. The PVC is obviously completely compatibe with the PVC wiring, although its friction coefficient is high. For low friction coefficient, you want polypropylene or teflon, but those will both be much harder to glue, due to being non-stick.
