Installation Instructions
Cast Stone Arbor
IMPORTANT NOTES:
 Before digging, check for underground utilities. The North American One Call Referral
Service at 1.888.258.0808 connects you to a national directory of utility companies.
 If installing onto an existing foundation, additional post brackets and hardware are
required and not explained within the arbor installation instructions.
Arbor Layout & Preparation:
1. Locate the arbor posts on appropriate centers to suit your walkway width, recommendation is
(51” - 57”). Width centers determines purlin overhang.
2. Dig (2) holes for a 12” diameter Sonatube (optional) below your local frost line or at local
building code requirements, on appropriate centers.
3. Trim the top of the Sonatube (optional) 4” below the finish grade.
4. Square off the top of the hole with 2” x 4” wood to create a 16” square form to create a
concrete pad for the cast stone base. Pads should be level to one another.
5. Prep the ends of the posts for anti-twist and lift, by driving (24) #10 x 2” long common nails
into opposite sides of the post (6 on each side) approximately 1” deep. This will leave 1”
exposed to set in the concrete.
6. Set the posts in the hole, maintaining the appropriate center dimension, with a minimum of
98” of the post above the finished grade. Square and secure posts as concrete cures. The post
will be cut to size after the concrete has cured for leveling.
7. Mix and pour the concrete around the posts. Smooth the surface with a trowel.
