Fischer 534996 Blister Duopower 5 x 25 S K

The fischer DUOPOWER offers very good clamping values thanks to the 2 components: the grey nylon component of high quality automatically activates, depending on the construction material, the optimal operating principle (expansion, lock, knot) for better clamping. The expansion wing of the red components reinforces safe expansion and offer added security to the gray components. Simple screw rotation and correct "removal" at the end. The screw does not overturn. The edge built into the head of the plug prevents it from sinking into the drill.

• Combination of two components of materials for higher performance.
• The flange prevents sliding into the hole.
• The serrated fins prevent rotation in the hole during installation.
• Easy to assemble: The narrow edge of the dowel prevents it from sinking into the drill.
• Two components for superior loads and intelligent operation (expansion, folding, knotting) depending on the bracket.
