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).

These supports can be used on lids that open up from the side, which are good for overhead installations, and on lids that open up from the top, which are good for crates, hatches, and tool chests. 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". They are reversible for right-side or left-side mounting positions.

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". Both are reversible for right-side or left-side mounting positions.

Providing constant resistance through the full range of motion, these supports hold lids open at any angle up to 70° or 90°. Simply raise or lower the lid and let go—friction keeps it in position. 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.

Supports for lids that open up from the top are often used on crates, hatches, and tool chests.

Supports for lids that open up from the side are often used in overhead installations.

Supports for lids that open down from the side allow lids to double as a work surface when they are open, similar to a drop-leaf desk.

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.).

Springs provide lifting assistance to raise and hold lids open—slightly lift the lid to get it started and the support will do the rest. Manually shut the lids and the supports will hold them in the closed position. 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". They are reversible for right-side or left-side mounting positions.

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. Reversible mount supports are for right-side or left-side mounting positions.

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.). Supports with a speed adjustment screw allow you to control their closing speed.

Supports that do not hold lid closed require a latch or lock (not included) to secure lids in a closed position. Supports that hold lid closed are designed to hold lids in the closed position.

Supports for lids that open up from the side are often used in overhead installations.

No separate hinges are required, these supports act as a hinge and lid support all in one. Springs provide lifting assistance to raise and hold lids open—slightly lift the lid to get it started and the support will do the rest. Manually shut the lids and the supports will hold them in the closed position. Often used in overhead installations, these supports are designed for lids that open up from the side. All 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". Mounting position is determined as you look into your cabinet or chest.

Gradually slow your lid's motion to prevent it from slamming open. To open lids, lower them and the support 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". Mounting position is determined as you look into your cabinet or chest. Reversible supports are for right-side or left-side mounting positions.
