Wood Fencing Learning Center

Fence Supply Inc. offers loops from BD Loops and National Loop. In this illustration we will be using the BD Loop for an example. For these example we will be installing under the following application

Application: Asphalt or Gravel Road

Step #1: Position and shape the loop on asphalt sub-base. Be sure to use the correct loop size. Refer to suggested loop size chart.

Step #2: Pull lead-in through ½ inch rigid schedule 40 or 80 PVC from loop yoke to gate operator 
detector location. Glue all PVC joints.

Step #3: Dig a 2-inch wide by 3-inch deep trench in the size and place of the loop footprint in step #1
and lead-in run to the detector. In the case of a Gravel Road, dig 7 to 10 inches deep.

Step #4: Fill the trench with one inch of sand base.

Step #5: Lay the loop and lead-in run in the trench on top of sand base and use supplied ground stakes to secure  the loop corners.

Step #6: Cover loop and lead-in PVC run with 2.5 inches of sand. A slight mound effect will take place in the sand as it covers the loop and lead-in PVC run. This will allow a good compaction of 
sand around the loop when asphalt is applied. In the case of a gravel road compact sand around       
loop then fill in with road base.

Application:Brick Pavers

Step #1: Determine loop position and footprint to include lead-in run to gate operator. Be sure to use the correct loop size. See suggested loop size chart.

Step #2: Dig a two-inch wide by three-inch deep trench.

Step #3: Fill trench with 1 inch of sand.

Step #4: Place loop in trench and run lead-in through schedule 40 or 80 rigid PVC. Glue all PVC 
              joints.

Step #5: Cover loop and lead-in run with two and one half inches of sand.

Application:Concrete

Step #1: Lay loop on top of the rebar (never below) and shape loop into desired loop pattern. Off-set loop pattern two to three inches to the left or right so it does not lie directly on top of rebar        pattern. Be sure to use the correct loop size for the driveway width. See suggested loop size          chart.

Step #2: Use cable ties to secure loop in place.

Step #3: Run lead-in below the rebar through schedule 40 or 80 rigid PVC and glue all PVC joints

Quick Tips: Easy Installtion

Step #1: Determine the placement of the yoke (intersection of loop and lead in wire) and secure it 
              in place. Pace off 8 foot 8 inches at 62° for a 4’ x 8’ or 9 foot 1 inch at 70° for a 3’ x 9’
              loop size and ground stake* or cable tie* the corner in place. See Figure A, Step #1              below.

Step #2: Place a stake or cable tie at the 4’ or 3’ leg of the loop the makes a 90° corner as shown below and marked as Step #2
             
Step #3: Place the last stake or cable tie to form a 90° corner marked as Step # 3 to form a 90°
              angle. See bottom drawings of Figure A.

                                  * Both ground stakes and cable ties are supplied with each loop.
