Saw-cut Installation Instructions
Preformed saw-cut installation tips and directions
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.

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.
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.

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.
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.
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 ).

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.
