Loops
Typical Loop Saw cut
Loop Size Chart
The loop size is based on the width of the driveway. If the driveway were 14' wide, the loop would be a
6'x6', the minimum. This is determined by subtracting 4' off of each side of the drive, which would leave
you 6'.
See chart below for number of turns per loop size, plus lead in.
The loop itself should contain between 90 & 125 feet of wire in the loop, plus lead in.

The location of the loop is also important. If a loop is located too close to the gate, it will detect the
gate itself, giving false operation. If the loop is too far away from the gate a small vehicle might not be
detected. Loops should be approximately 5' from the centerline of a gate when closed. See Loop

Corners should be cross cut as shown for
stress relief. 45 degrees is maximum turn
allowed. Saw cut width must be at least
1/8 inch for recommended wire. Lead in
slot must be at least ¼ inch for twisted
leads.
