About Selecting Shock Absorbers
To select the best shock absorber for your application, you need to find the energy capacity your application requires. Use this formula to calculate the energy capacity required to stop a horizontal-moving load. For example, if you have a 250-lb. load moving at 25 inches per second, your calculation is (250 lbs. ÷ 772) × 252 = 202.4 in.-lbs. energy capacity.
Note: Choose a shock absorber with a higher energy capacity than you calculated. Factors such as driving force or an inclined surface will increase the energy capacity required.
Energy Capacity (in.-lbs.) = (Weight, lbs./772) × Velocity2 (in. per second)
Spin-Weld Plastic Tank Patches
Repair holes in plastic tanks and containers with these patches. As you spin these patches with a handheld electric router, they melt into the surface of your tank for a seal without any joints. To hold these patches in your router, you’ll need the installation tool (sold separately).
For proper installation, you’ll want to use a hole saw to drill a hole that matches the For Hole Diameter listed and check that your router meets the speed and power requirements shown in the table.

Light Duty Adjustable Shock Absorbers
Also known as snubbers, use these shock absorbers in low-load, high-cycle applications. They counteract the energy of moving objects to prevent damage to equipment and material. Turn the knob to change deceleration to suit varying loads and speeds. Through-wall shock absorbers have a stud and nut under the removable knob for mounting through a panel or bracket.
