Tom, I am a refrigeration serviceman and this problem has come up a couple of times and each time we just muddled thru it and got a fair job of fixing it. Here it is. Some commercial walk-in-cooler door mfg use a nylon or similiar bristle brush for the bottom door wiper gasket (to keep the cold air in). The problem is that the concrete floors we set these doors on are very seldom level and the mfg provides a whopping1/8" or so adjustment on the wiper gasket. By now you see the door opens, but does not close because the bristles are bent and jam the door open. The only way the door will close is by nudging it. To remove the wiper assy. makes the doors look terrible and since there is no way of gaining more adjustment I trim the bristles about 1/8"- 1/4" and this fixes it. The problem is I can barely cut them with electricians side cutters. Tried tin snips, sharp scissors etc. to no avail. There has got to be a better way. I spent 2 hours today trimming about a 3' door wiper and both hands are sore. The bristles are about 1/8" thick and 3/8" tall and crimped in an aluminum channel. I think if you could clamp them in a metal break and score it with a utility knive they would cut. The problem is you can't hold them still. Any ideas? Thanks for any input you or anyone else can provide. Lyndell P.S. Did I mention that with good quality almost new side cutters I can only cut about 1/8" section at a time? I don't know if it is nylon or what. May teflon? :-) Brown to black color bristles. I am looking for a way to do this in the field, short of taking a tablesaw or something on the job. More specifically: I am looking for a miracle !
