LockMaster Gate sizing
|2-4m (8')||3m (10')||3-6m (12')||4-3m (14')||5m (16')||5.(18')|
Note the above chart is the maximum weight/length theoretically possible that a gate opener arm can handle.
It does not take into consideration dynamic loads like wind, snow and ice build up or sticky hinges.
Snow or ice can easily double the weight of the gate.
