Hole Punch Location:

  • Polyethylene is 4 mil or 6 mil and is protected with a strong ultraviolet inhibitor. These tubes are manufactured using a formation specified for the greenhouse environment and are fully guaranteed for one year.

  • Each tube is custom punched with proper diameter holes and spacing to conform with the specific equipment used.

  • Normal punch position is at 8 and 4 o'clock. For a heating application, 7 and 5 o'clock should be specified. 9 and 3 o'clock punching provides lateral movement. Edge punching can be done when only one row of holes is required and is excellent for under-bench heaters along sidewalls.
