® Installation Tips – Latitude® Pergolas Design Decisions Check that you are not placing a structure too close to a building, trees or your property lines. Confirm the location of any underground utilities. Your municipality may also have regulations concerning easements, line of sight, lot coverage and building permit requirements. Assembly Latitude Pergola kits include pre-assembled panels, which are connected on site with rafters and cross-rafters that finish and stabilize the structure. You will need braces or another person to support the panels while installing the rafters, and to right and place the pergola in its final location. Installation Latitude pergolas are designed to be free-standing above ground when assembled. If anchoring posts to concrete piers or slab or a deck surface, select saddles to fit a 2-3/4” post or bolt directly to a heavy-duty “L” bracket. If the pergola is to be anchored to the structure of a deck, calculate the finished height from the decktop surface, and trim post ends if necessary. Predrill for carriage bolts to fix to the supporting structure of joists and beams. Apply decking around posts for a professionally finished look. All cuts and large holes made in posts should be liberally brush coated with two applications of an end-cut preservative, to protect the exposed wood against fungal decay. You can look forward to many years of enjoyment of your Latitude Pergola. With time the colour will weather to a soft, natural grey, but the wood will continue to be protected against fungal decay for decades to come. Applying a sealing coat of weather repellent or stain will impede the natural fading of the wood. Latitude® is a registered trademark of the Cambium Group.
