INSTALL LEDGER USING MOUNTING BLOCKS
(ALTERNATE INSTALLATION METHOD)
Ledgers can be installed using mounting blocks for a totally concealed fastening
system. This installation method is primarily recommended for installations below a
casement.
On the back side of the ledger below the tongue are three pockets. These pockets are
made to accommodate wood blocks made from standard 1 x 6 nominal material cut
1 ½" long. Viewing the ledger from the front, the centerlines of the pockets are 8 5/16"
from the right end, 21 ⅞" from the right end, and 35 ⅜" from the right end respectively.
Dry fit ledger and mark location of the top and right end of the ledger. Blocks should be
fastened to the wall and located to align with the pockets. The top of the blocks should
be ¾" below the top of the ledger. The ledger is then placed on the panel as with the
previously described methods.
After placing the ledger onto the mounting blocks, drive a screw from the bottom of the
ledger into the mounting blocks. Adhesive should be applied to the blocks and to the
ledger using the method illustrated on the previous page.
LEDGER INSTALLATION Cont.
All products must be allowed to acclimate; removed fr om boxes and stored flat at
the installation site for a minimum of 48 hours or until properly acclimated prior to
installation. Heat and moisture cause expansion. Best results are obtained by installing
cool, dry product. NextStone™ does not warrant against gapping caused by expansion
and contraction.
