  • Anchor Type: HKD-D M12x50.
  • Hole Spacing (Top): 175mm horizontal by 170mm vertical.
  • Hole Spacing (Bottom): 285mm horizontal by 290mm vertical.

Ensure the anchors are installed securely into the concrete surface before attempting to mount the rail bracket.

Rail Installation

Follow these steps to mount the rail system:

  1. Install the HKD-D M12x50 anchors according to the specified dimensions.
  2. Position the rail bracket over the installed anchors.
  3. Secure the bracket to the anchors using the provided hardware.
  4. Tighten the fasteners firmly to ensure the rail is rigid and stable.

Cutting Setup

Once the rail is mounted, proceed with the rail alignment and wire saw setup:

Common problems

Rail instability during operation

Ensure all HKD-D M12x50 anchors are fully tightened and the rail bracket is flush against the mounting surface.

Incorrect rail alignment

Verify that the hole spacing matches the 175mm/170mm and 285mm/290mm dimensions exactly before drilling.

Before use

  • Verify the use of HKD-D M12x50 anchors.
  • Measure and mark hole positions: 175mm x 170mm (top) and 285mm x 290mm (bottom).
  • Ensure the mounting surface is structurally sound.
  • Check that all rail components are free of debris.
