What size Allen wrench is used for Closer adjustment?

LCN does not supply Allen wrenches.  The size allen wrenches that LCN uses, are standard sizes that every installer will have in their tool kit.

  • 3/32" Allen wrench for adjusting regulation valves: main speed, latch, and backcheck
  • 5/32" Allen wrench for adjusting spring power.
  • LCN offers a Green Wrench with 3/32” Allen wrench on one side and 5/32” Allen wrench on the other side – part number:
    • GHW1 for 1
    • GHW12 for a pack of 12
    • GHW100 for a pack of 100

The exception is, if the customer orders a metric screw pack, LCN does supply the Allen wrenches.
