Jenkin A-lign Concealed Fix is our latest design-led solid timber weatherboard cladding system. It takes the features of our proven original Jenkin A-lign system, and adds the advantage of a concealed nail-less fixing that is fast and easy to install. Simply place and nail the structural cavity batten (machined with precision-cut lock-grips) to the wall, and connect the batten's lock-grip to the precisely machined cut groove on the weatherboard. Then apply the robust rubber lockstrip to lock firmly into place.

Priming or painting when the weatherboard is above the EMC can result in the weatherboards shrinking after installation or painting. If in doubt check with a moisture meter.
