These commercial-grade, over-extension soft-closing drawer runners are great for many applications including kitchen cupboards and high-end furniture construction. Each runner set has a maximum carrying capacity of 45kg and are designed as side mount drawer runners.
The soft-close mechanism has been rated for 1,000's of closing movements and adds a quality touch to the drawer closing.
These runners will over-extend their installed length by 25mm so you can easily clear the drawer above and require 12.7mm clearance on either side (25.4mm overall) between the drawer and carcass.
The length listed is the length of the runner closed - add 25mm for the the extension travel to this length.
