• 8450FM/8455FM soft-close slides close at the optimal
speed due to the perfect balance of dampening and
spring forces.
• Slides that close too fast have little to no dampening effect.
• Slides that close too slow have poor closure performance.

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 traditional linear
spring designs.
