replace plastic brooms , which used rollers with rubber tracks that stopped gripping the bars after a while. This design is a snap fit with vertical rubber teeth that grip the post with the pressure of a metal clip pushed outward. I see 2 possibilities for failure here: when the rubber loses its nature and when the metal gets tired and no longer applies pressure. Time will tell, but for now it's holding up very well and works with supports of different thicknesses. But what about the assembly? Not exactly a smooth process. But there are no instructions. Find a spot, find some wall studs, line them up, mark holes and drill some holes. wall anchor. Interesting. The plastic is brittle and I broke the first one by tapping it. My wall doesn't support stairs so there are studs in the odd places I installed these (maybe a fire barrier) and I almost all had anchor holes that went through the drywall and into the wood. Great for strength, but the second issue is that the screws that come with it are an inch long and not long enough for MY particular situation. I replaced some longer screws to use the wood and trimmed the anchors so they could cut into the wood (see photo). If you're just mounting to drywall, the included anchors will be fine. may be. It takes a lot of strength to push and pull brooms and tools from the handles. I understand why they include tape because wall anchors alone may not be enough. I highly recommend securing the center hole with a bolt and also using tape. So I basically used my own screws and a few of my own anchors. Decorative cups and screw caps are a good idea, but in practice caps are not suitable. did not stick, and an attempt to tap on them immediately deformed them. Spring. It's in the garage and the way it looks doesn't bother me too much. Overall it does a good job of holding a couple of brushes and a mop handle, very happy with it.
