HOW LOOPS WORK (continued) Explaining Loops to Your Customers
Selling Loop Systems
We’re on the Installer’s Side
By Brian Dickson, BD Loops
Shadow/Phantom/Center Loop:

any installers don’t fully understand the function of this loop, which can ma e it hard to understand
why it is so important on swing gates.

The Shadow Loop is placed under the swing path of a swing gate. This loop will check to see if a vehicle
is within the swing path, before the gate closes and/or opens (depending on the gate operator). The
gate will not move if a vehicle is within the swing path.

The shadow loop is very important. On a 12ft single swing gate, there is 20ft of undetectable area
between the inside and outside reverse loop that a car can easily fit into.

Not everyone looks at a gate to determine how it opens. Guests and visitors can easily stop in a gates
swing path while waiting to exit and without a shadow loop their car could be hit by the gate.

Reverse Loops:

Reverse loops hold the gate open or reverse a closing gate if a vehicle is detected. Reverse Loops offer
customers peace of mind, and prevent panic and risky actions when a gate is closing.

These are common scenarios where reverse loops are important:

Vehicle tailgating/follow-through, without a reverse loop the gate could close on vehicles following
another car through an open gate.

ou’re exiting and find a child’s bi e s ateboard toy bloc ing your dri eway exit, you get out of the car
to move the bike and the gate starts closing on the vehicle.

A guest leaving the property inches up to the street waiting for an opening to pull out of the driveway, if
they live on a street with high traffic, or where children play in the street you are not always able to exit
quickly.
