- 5 of 5 SOSS 101 Invisible Hinges April 8th, 2026
by Richard from Mukilteo, WAThere is a marked difference between the SOSS 101 invisible hinges and those made in other countries. The quality, fit, finish and the smoothness of operation of the SOSS hinges is just superior. Yes, they cost more but is your project worth the cost in long term.

- 5 of 5 Pretty ingenious March 3rd, 2026
by Travis from Golden, COThese things are super cool and seem like they solve some problems in a unique way. But beware: they're pretty fragile! Don't expect to be able to test fit them and remove them over and over, or you'll break them (speaking from experience)

4 of 5 Pretty good December 30th, 2014
by Joseph from Spokane, WABought the 12 mm barrel hinges for some fly boxes. They were pretty decent, but not all of them were created equal. Some of them out of the box were quite a bit stiffer and grittier feeling. I used white lightning dry lubricant to loosen them up, seemed to work alright. I recommend investing in a good marking gauge, a quality 12 mm brad point bit and an accurate drill press. Your layout has to be spot-on with these, there's no room for error or adjustment. Over all I was pleased with the purchase, ordering from CabinetParts.com however is another issue. $14 for shipping a tiny package in snail mail is ludicrous, not to mention the tracking number I received from them was for somebody else's order. Hope this helps

The drawer pulls are good quality and have a nice finish, but the quality of the long fasteners is very poor. The hardware is made so can be cut easily but the threads are very poor and cross thread easily. I will have to buy better fasteners, I donโt see

Fast delivery and it seems to be of very good quality. Exactly what I needed to save my back from digging out items from our 1960โs blind corner cabinet. Should have bought one of these years ago! Install was pretty easy. My husband did it in under an hou

Purchased my Blum 24โ drawer glides, and received them 1 week later. I was shocked by how fast my order was processed, shipped and arrived! I have three other projects planned for this summer and will definitely order all my parts for my upcoming projects
