Appendix A – Anchor Management

♦ It can be argued that the wall anchor is the most critical component of the wall mounted

backstop system. All of the weight of the unit, as well as the load introduced through play and
use of the equipment, ultimately must be supported by the wall anchors. Preparation of the
wall, drilling of the holes in the proper location and depth, and most importantly correct
selection of the type of anchor are all critical steps in the installation process.

♦ Due to the fact that there are so many different types of walls Jaypro is not able to supply the

wall anchors with the backstop unit at the time of shipment. We do, however, stock most
common types and you can purchase the anchors from us directly.

♦ All wall anchor hardware should be a minimum of ½” diameter.

♦ The following four pages lists three of the most common wall anchors. Before drilling a single

hole you must verify the type of wall you will be installing against and then procure the
necessary type and quantity of anchor to guarantee a successful installation. Immediately below
is a table listing acceptable anchor types for given wall compositions.

The Hilti Kwik bolt 3 comes in two varieties – Expansion anchor and Adhesive anchor (sometimes
referred to as a chemical anchor). The Hilti Kwik Bolt 3 is the only anchor approved in many
California districts due to its endurance under seismic loading. It has extremely high load capacities,
but is has particularly stringent preparation steps. Consult Hilti’s own website (

www.us.hilti.com

) and

installation instructions supplied with anchors for complete site and equipment preparations. Shown
below are general steps for installation for reference only.
