What is the difference between the 3-rail steel gate kits and the 2-rail steel gate kits?
A3.) The difference between the 2-rail kits and the 3-rail kits is the height of steel verticals in the gate kit and the quantity of horizontal rail brackets. The 2-rail gate kits are 45″ high and ideal for building a gate 4′ high which typically has only two horizontal rails. The 3-rail gate kits are 60″ high and are ideal for a 5′ high gate or taller which normally has three horizontal rails. Heights of steel gate kits cannot be modified. There are steel mounting tabs which accept the wood 2 x 4 (2 x 4 not included) preinstalled for horizontal rails which will hold the pickets. See pictures below.
