METHODS OF ANCHORING
WARNING
The installer must match the correct type of wall fastener with composite material the wall
is constructed of for a safe and permanent connection. Failure to do so could result in a
catastrophic failure, causing serious injury, or even death.
THRU-BOLTING
The only approved Porter methodology of attachment of Wall Mounted Backstops is to
thru-bolt a minimum of two anchor points at the backstop extension structure, and a mini-
mum of two thru-bolts at the chain support (should your backstop be provided with such),
in conjunction with the appropriate anchors, as indicated on your project specific installa-
tion drawings. Detail “B” is for illustration only, and may not relect your projects’ anchoring
requirements. Do not drill less than 9” from any door or window opening, and never attach
to the top course of a block wall.
Please also refer to the General Anchoring layout ex-
amples in this manual.
