Inside Corner Ledger
Straight ledgers feature a sloped angle away
from the structure to assist with shedding
moisture. This angle makes mitering a straight
ledger almost impossible.
CORNER LEDGERS
✓
Corner Ledgers Are Designed to Fit Seamlessly
Above Corner Panels
If obstacles such as electrical boxes, windows, doors or hose
spigots are part of your install, do not subtract these voids from
your total number of panels and accessories. Most cutting
mistakes are made in these areas, you may need the extra pieces.
TIPS FOR SUCCESS

Corner Ledgers Butt Up Against Straight Ledgers

Plan for One Return Piece for Every One Full
Panel in Height
Be sure to plan on staggering the seams created
when two return panels will stack on top of one
another. If your installation requires cutting of a
return piece, always recreate the shiplap edge.
