QM-QBP-17.5-M1 QBase Post Style Mount
Product Information:
The QBase Mount is a mounting system designed for attaching
solar panels to a roof. It consists of a post, base plate, and top
hardware. The mount is available in size A and can be used with
post lengths of 3.25, 4.5, 6.5, 8.5, 11.5, 12.5, 14.5, and 17.5
inches. The mount weighs 1.161 lbs and ships without fasteners.
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
Product Usage Instructions:
- 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.
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.
