The above photos shows an untreated Larch Glemham straight top gate and Tongued & Grooved Board Wall Top Side panel. This timber can be left to weather naturally but is also the ideal choice if you wish to stain or paint as it will give a beautiful finish. Also available in Scandinavian Redwood or Oak and Iroko hardwoods. 

Tongued & Grooved Boarding is strong, smart and solid. The design compliments many of our solid gates and so it is a great go to solution for a wall top side panel. 
As with most wall top fencing it is fixed to independent full height posts behind the wall so it adds no strain to the existing wall structure making it perfect for older walls.
Constructed on site it is available to any height , shape and formation.

Side panels and Gates are made to measure so can be adjusted to suit any situation.
