Specification

Frame anchor tested and approved in more than 90 stone types and in aerated concrete. Also for window installation (approved for mounting in reveal). With countersunk head screw made of zinc plated steel

Immediate load-bearing capacity — no waiting

Almost no distortion of the wall plug body

Low screw-in torque of the plug screw

"Slight" spreading of the anchor

High load-bearing capacities

Expansion in four directions

2 insertion depths

Improved load transfer in solid and hollow construction materials

Even, continuous load distribution across the entire expansion area

The hammer-in stop prevents premature expansion of the anchor during installation

Easier installation

Pre-assembled wall plug body and special screw

Anchorage via friction locking between wall plug body and anchoring base

Push-through installation

Proof of Performance

General construction permit Z-21.2-1838

European Technical Approval ETA-08/0190

Fire resistance:

Concrete: Tensile and transverse loads, R30, R60, R90, R120 (in accordance with Technical Report TR 020)

Masonry tensile load: F30 (solid sand-lime brick, solid brick, hollow sand-lime brick) Transverse load: F30, F60, F90, F120 (vertically perforated brick, hollow sand-lime brick, solid brick, aerated concrete)

Notice

Drill perforated and hollow blocks with a rotary drill (without impact mechanism)

Drill cuttings must be removed from the drill hole

For anchoring in solid brick and solid sand-lime brick, we recommend that you perform pull-out tests due to the differences in brick manufacturing

Fire resistance:

Concrete: Tensile and transverse loads, R30, R60, R90, R120 (in accordance with Technical Report TR 020)

Application

Application area

Multiple attachment of non-load-bearing systems with approval

e.g. for attaching façade, ceiling or roof substructures (made of wood or steel), wooden beams, wooden laths, metal brackets, metal rails, suspended ceilings, cable conduits, angle brackets, profiles, wall-mounted cabinets, shelves etc.

Anchoring bases

Standard concrete

Masonry walls (solid brick, solid sand-lime brick, vertically perforated brick, hollow sand-lime brick, hollow lightweight concrete blocks, solid bricks and blocks made of lightweight concrete, concrete bricks, aerated concrete), brick ceilings, prestressed concrete hollow slabs, reinforced aerated concrete, gypsum wallboard

The galvanised screw can be used outdoors or in wet rooms (if installed carefully) provided the area around the screw head is protected against moisture or rain so that moisture cannot penetrate the anchor shaft (suitable paint).
