Review on Siemens 52ABH6 Hole Plug Steel by Ray Richards

Possibly the most exquisite end cap I have ever seen. Perfect roundness and enticing curves will make you want to poke holes in anything so you can use one of these stunningly beautiful hole plugs to hide them. The silky smooth bluish gray finish reminds me of the gray rocks of the Farne Islands before sunset. The soft, spongy gasket is a beautiful thing, and being crushed during installation brought me to tears. A gleaming silver wing nut threads onto an M5 .8 bolt like a grand prix racer. I'm so glad I discovered them.
