The attached cover protects the scale while you carry it.

Calibrate your scale with these test weights.

Our most accurate test weights, these are often used to calibrate precision scales.

These test weights come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy.

A handle makes it easy to move these test weights.

Install these balancers on a vertical frame to suspend, lift, or lower objects that move vertically in a track such as windows, doors, and panels.

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 support will slowly and softly do the rest. Manually shut the lids and the supports will hold them in the closed position.

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.

When used in pairs, these supports can hold lids weighing over 200 lbs., which is three times more than our other lid supports. 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.

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.

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