Gate Extensions

Extensions for all Major Gate Manufacturers

Gate extensions allow you to increase the width or the height of a gate. You will find that when you add your gate choice to the basket on our site, there will be the associated gate extensions that are designed for that selected gate model. If you already have a gate and need to modify it using an extension, we clearly post which extensions go with each gate model.
