Expansion plug SB

The installation-friendly nylon plug

The fischer expansion plug SB is the original and the proven classic millions of times for decades. The plastic fixing is made entirely from high-quality nylon. As a result, the plug is particularly robust during installation and guarantees permanent security. As the plug only expands in two directions, it is possible to direct the expansion forces so that they run parallel to the edge of the building material by turning the plug. This prevents the building material from spalling due to fixings close to the edge. The fischer expansion plug SB comes complete with angle hooks and is recommended for fixings in solid building materials.

Assembly Instruction

  • The expansion plug S is suitable for pre-positioned and push-through installation.
  • When screwing in the screw, the expansion plug S expands in two directions, thus providing a secure anchoring in the building material.
  • The required screw length is given by the plug length + plaster and/or insulation material thickness + fixture thickness + 1 x screw diameter.
  • Suitable for wood and chipboard screws.
  • The edge distance must be at least one plug length.
  • For installations close to the edge, turn the plug so that the expansion force acts parallel to the edge.
