Saw-Cut Instructions without TB-Kit

Determine and mark loop position and footprint
to include lead-in run to gate operator. If the
pattern is too large the loop will not fit, so make
your measurements slightly smaller than larger,
excess can be placed in the yoke area. Corners
should be marked with a 45° dog-ear cut that
measures 5 ½ x 5 ½ x 7 ¾ inch. See reverse
side of this sheet for a template. Be sure to use
the correct loop size.*

3/16” inch or 1/4” saw-cut blade with a minimum depth of 1 ¼ inch and a maximum of 1 ¾ inch is
recommended. Cut into the installation surface following the marks previously made. No backer-rod is
required if using a 3/16” saw-cut blade, but when using a 1/4" saw-cut blade use backer-rod or wrap
electrical tap every 2-3’ to serve as backer-rod.

A wider groove is needed for the yoke (where the loop meets the lead-in). Drop the blade several times
to make a 5/8 inch wide groove that is 6-8 inches long.

Prepare to insert the loop into the saw-cut groove. Start by positioning the red line on the loop (mark
made at the factory) at the corner opposite of the yoke. Do not fully insert the loop into the saw-cut

groove at this time. Partially insert the loop into the saw-cut groove, red side down, adjusting the

position of the loop to fit the yoke. After aligning the yoke start at the red mark opposite of the yoke, fully
push the loop into the bottom of the saw-cut groove, do not use a tool that has a sharp edge. BD Loops
recommends the use of its PR-3/16” (Pizza Wheel) to push its saw-cut into saw-cut grooves.

Seal saw-cut groove with a proper loop sealant, use of a 3/16” saw-cut blade can save 50-60% on loop
sealant because of built-in backer-rod. Weather, humidity, and temperature will determine which type of
sealant to use. Apply loop sealant to a dry and clear surface, use of the BD Loops Groove Cleaning Air
Wand can help remove debris and dry the groove quicker. Use the BD Loops 3/16” Sealant Tip Applicator
to effectively fill the groove from the bottom up in one pass.

Saw-Cut Instructions using TB-Kit

Use of the BD Loops TB-Kit will insure a correct
sized cut every time by using the loop itself to
measure and mark lines.*

1. Insert loop in kit and drill holes.

2. Chalk lines.

3. Exact pattern every time.

*In depth instructions supplied with kit.

Basic loop layout guidelines to follow

Reverse and Exit Loops

 4ft from the gate/door.
 Swing gates require 4ft from its

complete open and closed position.

 2ft from each curb.
 4ft from every other loop.

Detection height of loop is determined by 2/3 of the short leg of the loop.

Residential 4ft short leg (Detection of standard size vehicles only - 32” detection height).

Commercial 6ft short leg (Detect higher bed vehicles – 4ft detection height).

Shadow loops

 Loop lays under the swing path.
 3-4ft from the gate in its complete open

and closed position.

 If the shadow loop is under a single

swing gate, 0-2ft from the curb.

Visit our website to learn more, and download your own free copy of the Loopalator – The Loop Layout Calculator. Just by
knowing the driveway width, type of gate, and type of loop (direct burial or saw cut) you can easily calculate the sizes of loops
needed for any job, and print out a detailed layout plan to give to installers.

How to properly exit the

roadway

 Drop the blade to the bottom at the edge

of the roadway.

 Always exit lead-in through the bottom.
 6-8 inches below the bottom of the

surface material.

 Always run lead-in through PVC conduit.

If you have a gopher problem lead-in
can be run in metallic conduit.

Made the cut too small?

 Push the yoke down the lead-in run,

up to 2 ft.

Made the cut too large?

 Cut the dog ear corner opposite of

the yoke to make the loop’s

perimeter shorter.
