About 20" 200Lbs/889N Lift Support Struts Gas Spring
How to Choose the Correct Gas Struts for the Job? * Step 1. Measure the Length of your lid where you will mount struts; * Step 2. Weigh the lid – Use a pole and bathroom scale to weigh at the position you will mount gas struts, usually at the position 30%-50% from the hinge; * Step 3. What Force gas struts you require If the scale read 200 Lbs we recommend you choose the 200×2 (400lbs) strut kit at least! (We recommend 2 Pcs Set 200 Lbs Lift Supports) * Step 4. What Size gas struts you require We suggest the length of a strut equals about 1/2-2/3 of the lid length. How to Install the Gas Strut for the Job? * IF you will install them on your truck or camper shell, it is super easy; * IF you will install them on a new build, please install as per the following step: * Mark a point at 1/3 from the hinge to the opposite side of the lid as the upper mounting point; Open the lid to the height you need, fix the upper bracket of strut and easily get the lower mounting point as image left shows. * Pressure could be adjusted as the method below: * If you feel it is is too weak, move the mount point on the lid opposites to the hinge direction; * If you feel the pressure is too strong when open/close , move the mount point on the lid closer to the hinge direction to reduce the pressure played by the struts.
