So we had two sunny days recently, before winter descended on us AGAIN, and in celebration I visited my favorite TrueValue hardware store with a stub of PEX tubing in my hand. The plan was to put a damper on the jitterbugging going on under the sink from the water pump and associated piping.
Sure enough, they had rubber-cushioned clamps and pipe insulation, so I bought some.
Later, as I was doing my taxes in the Burro-office, my mind wandered off-topic AGAIN and it occurred to me that maybe this foam tubing insulation (5/8" ID and 1 1/2" OD) might multitask, especially since they now put a decent adhesive on the edges of the split.
Since we bought the trailer in 2000 I have snubbed my bald head on the top of the door frame numerous times, forgetting that it is low and dangerous if you move fast and carelessly. Blood has flowed and scabs have formed many times from me and various visitors. I even prevailed on Frederick to part with one of his rubber duckie decals and mounted it over the door as a reminder. Probably a 30% reduction in blood flow.
Turns out that the weatherstripping was the same thickness as the foam rubber. So I removed it and stuck the foam roll around the offending edge and tried the door to see if it was too thick. No, it was just right. So I cut and trimmed it, and the adhesive edges made it stay firmly in place.
So if you have a similar door (a generic RV door with inner screen door. Ugly but practical) it may be worth a try. Certainly cheap, and takes care of the worst edge on the frame. I may even clad it in some curtain material for effect.......
