General Guidelines

• The GSC is designed to clamp anywhere on the body of the Gas Spring, and it does not require a groove or feature on the Gas Spring body to clamp onto. The diameter of the Gas Spring is the only thing that you need to consider.

Clamping Anywhere on the Z-Axis

• We do NOT recommend using the GSC on “uncontained” Gas Springapplications.Forexample,GasSpringsusedto“drive”aLifterBarorRackfromabove.

• Screws with a nylon patch should be used (provided).• Back-upisrequiredtosupportthefullloadoftheGasSpring.• Werecommendthemountingsurfacebeaflatmachined

• Clamp stays Oriented during assembly and disassembly

• Gas Spring stays in the center of the hole since clamp is oriented by 2locations

• GasSpringcanbepositionedtightup against another detail due to the “Open” design

Negative perception of Flat Head Screws in Dies?HereiswhatwefoundandwhyitDOESNOTapplyinthisapplication

There is a large amount of contact surface betweenthetaperontheFlatHeadScrewandtheblockitissecuring.Thisgenerallypresents a problem only when the screw is beingremovedbecausethesurfacefrictioncombinedwiththe“smaller”hexsizecanmakeitdifficulttoloosen.

Traditional ApplicationTheFlatHeadScrewonlymakes

POINT contact with the Gas Spring Clamp, so there is not a

large surface area that can cause theFlatHeadScrewto“seize

up” when removing.
