Keep environments free of contaminants—with plastic bushings, there's no metal-to-metal contact that can release particles as these supports open and close. Manually control these free-moving lid supports through their full range of motion. Raise the lid until the hold-open mechanism on the support is engaged; slightly lift it again to release the hold and close the lid. To secure the lid in a closed position, use a latch or lock (not included; see our clean room magnetic latches).

They are rated for maximum lid weight—do not exceed the weight listed. The supports can be used individually but should be used in pairs for lids longer than 24".

Hold heavy lids open with these supports. Raise the lid until the hold-open mechanism on the support is engaged; slightly lift it again to release the hold and close the lid. To secure the lid in a closed position, use a latch or lock (not included). All of these supports are rated for maximum lid weight—do not exceed the weight listed. They can be used individually but should be used in pairs for lids longer than 24".

Also known as hatch springs, these supports are commonly used on hatches and other top-opening lids. Raise the lid to extend the spring, which props the lid open—an internal cable keeps the spring from overextending. Press the center of the spring to release the hold and close the lid. To secure the lid in a closed position, use a latch or lock (not included). These supports are rated for maximum lid weight—do not exceed the weight listed. They can be used individually but should be used in pairs for lids longer than 24".

To eliminate slamming and smashed fingers, these supports automatically pull lids shut when they approach the closed position. Raise the lid until the hold-open mechanism on the support is engaged; slightly lift it again to release the hold and close the lid. These supports can be used individually but should be used in pairs for lids longer than 24". Mounting position is determined as you look into your cabinet or chest.

All of these supports are rated for torque instead of maximum lid weight. Calculate your lid's torque and make sure it falls within the range listed—too much torque will cause your lid to slam; too little will prevent it from closing. Torque = Lid Height (inches) × 0.5 × Lid Weight (lbs.).

Requiring less space to mount and operate, these supports are often used on small cabinets and enclosures. They gradually slow your lid's motion to prevent it from slamming open. To open lids, lower them and the supports will slowly and softly do the rest. Manually shut the lids and the supports will hold them in the closed position. Designed for use on lids that open down from the side, these supports allow lids to double as a work surface when they are open, similar to a drop-leaf desk. They can be used individually but should be used in pairs for lids longer than 24".

All of these supports are rated for torque instead of maximum lid weight. Calculate your lid's torque and make sure it falls within the range listed—too much torque will cause your lid to slam; too little will prevent it from closing. Torque = Lid Height (inches) × 0.5 × Lid Weight (lbs.). An adjustment screw allows you to control the opening speed.

Commonly used on hood and trunk lids, these simple three-piece rods telescope from 18 _1/2" to 46 _3/4" to prop lids open at a variety of angles. A rubber tip at each end protects your surfaces from damage.
