Functionality:
The PA 4 is suitable for pre-assembly installation. The insertion of the metric screw expands the brass anchor in the front area, securely anchoring it in the substrate. The screw length for flush anchor installations is determined by the anchor length plus the thickness of the attachment, which corresponds to at least the screw length.

Applications:
Basement shelves, wooden and metal substructures, instantaneous water heaters, units, control cabinets, bump rails, handrails.

Advantages:
The compact design of the brass anchor reduces drilling effort and ensures quick installation. The special surface structure of the brass anchor prevents it from rotating in the drill hole, achieving greater installation security. The internal thread allows the use of commercially available metric screws or threaded rods and enables flush disassembly and reusability of the fastening point, providing high flexibility.

Building materials:
Concrete, sand-lime solid stone, natural stone with a dense structure, solid bricks.
