The Knape & Vogt 8455 is quite honestly the holy grail of side mount drawer slides. Not only will you find mind blowing features like 1" over-extension slide members, micro balls for ultra smooth motion & telescopic member movement but Knape & Vogt has integrated all of this bleeding edge technology into a smoothalicious soft closing platform that's so groovy you may get motion sick just thinking about it.
Honestly, this is a one of the finest soft closing drawer slides manufactured today. Knape and Vogt has been making drawer slides for over 50 years and have become the standard for craftsman across the world. The Knape & Vogt 8455 includes a limited lifetime warranty so you can rest assured that this is a quality product.
