Ceiling nail FDN II

The installation-friendly push-through anchor for multiple fixings

The fischer ceiling nail FDN II is a zinc-plated steel push-through anchor. The FDN II is approved for multiple anchorings of non-structural systems in concrete. The fischer ceiling nail FDN II is ideal for anchoring wire and nonious hangers for suspended ceilings, ventilation systems, and metal profiles in cracked concrete. The European Technical Approval and classification as per fire resistance class R 120 ensure added safety. The ceiling nail is installed time-saving using a push-through installation and is hammered into the drill hole.

Product Description

  • The simple active principle allows for cost-efficient hammerset installation.
  • The new short version FDN II K with reduced anchorage depth ist faster to install and reduces reinforcement hits.
  • The flush-sunk expansion nail signifies the complete expansion of the anchor, and thereby ensures minimum movement when under load.
  • The fischer FDN II can be installed without cleaning of the drill hole.
  • The head embossing offers a simple control of the anchoring, and thus saves time.

Assembly Instruction

  • The FDN II is suitable for push-through installation.
  • The FDN II ceiling nail is driven into the drill hole with a hammer until it is firmly in position. Do not hit the expansion wedge at this stage.
  • Then, drive the expansion wedge in flush to the nail head. This causes the FDN II to expand against the drill hole wall.
