Which Gas Strut Do Need

We step you through The General Rules and The Formula which tell you exactly what Force/Newton and Length you want and then we help you choose brackets.

STEP 1. Measure the length of lid
Distance from the hinge point to the edge of thelid.
The Extended Length of Gas Strut ≈50% of the Lengthof the Lid.
E.G.length of lid is 30inchyou need a15 inch gas strut.
STEP 2. Weigh the lid
First method,unscrew the lid from the hinges and use a scale to weight.
Second method,move the lid to 90 dgree,use a pole and bathroom scale to weigh at the mount point.
Allow the weight of the lid through the pole to show a reading on the scales in Kg.
STEP3. Calculate the pressure
E.G. reading of 20Kg,1KG=10N,so a 20kg lid means that (G) equals 200N.
Ifyou are goingtouse2xstruts onthelid you can halve the amount of pressureineach strut.
