For better stabilization of gates and for preventing it from tipping
over these high quality ALEKO
rollers are mounted vertically on both sides of the gate. For proper
stabilization a pair of these rollers would be required but they are available
and sold individually. They are made of UV protected hard plastic and are
designed to withstand rigors of most extreme climates. These rollers will last
for years with very less maintenance and you can easily fix these to the posts
of your gate through welding or bolting.
