Installation Tools Required: Drill and impact gun with appropriate bit
and driver for selected fasteners, one tube of sealant compatible with roofing
materials, pencil,chalk line.
Note: The QBase Mount ships without fasteners, allowing the project
engineer to specify the fastener that best fits the project requirements.
Prior to installation insure you procure the appropriate type, size and
quantity of fasteners for your application. For rafter attachment, use two
5/16” x 3” Stainless Steel lag screws, ensuring minimum penetration of 2”
into the structural members Locate the desired mount placement per the plan
set. The mount can be attached to structural members or direct to the roof
deck based on site-specific criteria. Using the base as a template, mark the
penetration points with either a pen or light drilling. When attaching to a
structural member, use two opposing holes on the base plate, parallel to the
structural member. Drill pilot holes for the fasteners based on American Wood
Council recommendations. Make sure to drill perpendicular to the roof.
Backfill the pilot holes with a sealant compatible with roofing materials.
Prior to attaching the base to the roof, place the grade-8 hex bolt into the
bottom of the base. Fully seat the post into the base, using slip-joint pliers
if necessary. Attach the base and post assembly to the roof with the fasteners
specified for the project. Attach the top hardware to the top of the post.
This ensures the post will be sealed from weather exposure before racks are
installed. You are now ready to flash the mount, roof around it, and attach
racking. For built-up roofs and membrane roofs, be sure to use manufacturer-
specified flashing methods or utilize the services of a certified roofer.
