Installation & Maintenance

• Installation: The RS socket should be set into concrete generally in accordance with International Standards or good Codes of Practice for post installation.
  • Prepare hole at least 75mm deeper than the overall height of the RS socket. If depth for RS socket cannot be achieved, the unit can be shortened on site.
  • Compact at least 75mm of MOT type 1 granular material in base of hole for drainage.
  • Position RS socket in the centre of the hole and rotate its head to the required orientation. For cabled installations, connect ducting from a remote chamber to the swivel bend on the socket, leaving a draw cord in the base of the RS socket bend.
  • Remove locking lid, loosen the two M16 locking set-screws, and remove the pedestrian plug.
  • Install a levelling post (stump pole) in the RS socket, fasten the locking set-screws, and replace the locking chamber lid.
  • Surround with the required amount of concrete (ST4 mix or stronger), using the stump pole to achieve a vertical level.
  • Once vertical level is achieved, compact concrete.
  • Once concrete has been compacted and has begun to cure, carefully remove the stump pole and lock the pedestrian plug in place.
  • Replace the locking chamber lid and secure in position. Finish footway with the required surface when concrete has cured.
  Refer to the RS socket installation guide for EN40-3-1:2000 foundation guidelines. For detailed foundation sizing on specific site conditions, contact your supplier.
• Maintenance: The high-strength, reusable design minimizes maintenance needs. Its ability to survive vehicle impact and facilitate easy removal/replacement reduces disruption and expense. Supports maintenance and seasonal schedules. Technical drawings for all sockets are available from IPL group.
