New Force Management
TM
(FM) from Knape &
Vogt is the next generation of soft-close drawer
slide technology. FM technology establishes
a new standard in soft-close functionality by
delivering superior performance in dampening
action, effortless drawer opening and smooth
operation.
8450FM/8455FM slides include a patent-
pending Force Management
TM
module that
utilizes an innovative rack and gear system.
This clever system places mechanical forces
where they are needed to significantly reduce
the effort to open a drawer and to deliver the
effective drawer closure that customers expect.
All this is built on the time-tested KV 8400
slide platform, making 8450FM/8455FM slides
the smoothest and easiest soft-close drawer
slides to install and operate.

8450FM/8455FM soft-close slides have:
A lower peak pull force – making them the
easiest soft-close slides to open.
Significantly less drop off force at the module
release point – eliminating the "jerkiness" of
