About HDPE Handholes

Advantages:

  1. Polyethylene handholes will not crack or break in cold weather.
  2. Lightweight and very easy to handle and install by one person.
  3. Round configuration is easier to square holes during drilling process.
  4. Extend life of drill bits and save labor due to material being easier to drill through.
  5. Taper of barrel is smaller at top versus bottom prevents frost upheaval.
  6. Round configuration will not allow cover to fall into handhole base as other configurations would do.

Serve important functions:

  1. Drainage for conduit system
  2. Provides a protective enclosure for bending the conduit without damaging wires

  5. A junction for conduit coming from different directions
  6. Creates the ability to pull wires over long distances
  7. Polyethylene handholes will not crack or chip regardless of temperature
  8. Handholes are easily repaired if damaged by plows or mowers
  9. These handhole/pullbox units are made with only nonconductive material for safety reasons

 

Installation Procedures:

  1. Place handhole, frame and cover on bed of tamped coarse aggregate for drainage.
  2. Remove Cover and insert 2,  2″ x 4″ boards into handhole and crisscross them inside barrel as high in barrel as possible to support round shape during backfilling.
  3. Tamp fill material evenly around barrel with cover on barrel.
  4. If extension is not required then screw 6 stainless steel screws through frame collar located on lower portion of frame to inside wall of barrel and replace cover.
  5. If extension is required then insert extension into barrel and replace frame and cover and complete tamping around extension.
  6. Remove cover and place 6 stainless steel screws through lower portion of frame into extension and replace cover and to top of frame and cover.
