Frame anchor tested and approved in more than 90 stone types and in aerated concrete. With M6 connecting thread for e.g. securing pipe clamps in electrical applications. Made of A4 stainless steel

Universal frame anchor (concrete, perforated and solid brick masonry, aerated concrete)

Anchorage via friction locking between wall plug body and anchoring base

Push-through installation

Immediate load-bearing capacity — no waiting

Virtually no movement of the wall plug body

Low insertion torque of plug screw

"Slight" spreading of the anchor

2 insertion depths (h_nom = 50 + 70 mm)

Expansion in four directions — high load-bearing capacities

Improved force transmission 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

Less installation work

Wall plug body and special screw are pre-assembled

Saves an additional U-washer and prevents contact corrosion

Proof of Performance

W-UR 8, W-UR F 8 (galvanised steel, stainless steel): General construction permit Z-21.2-1838

W-UR 8 and W-UR F 8 (galvanised steel, stainless steel): European Technical Approval ETA-08/0190

Wall plug body made from high-quality polyamide

Fire resistance W-UR 8: 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)

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.

Drill cuttings must be removed from the drill hole

Application area

The anchor has European Technical Approval for use in multiple attachment of non-load-bearing systems (e.g. façades, suspended ceilings etc.)

W-UR, W-UR F can be anchored in the following 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 solid blocks made of lightweight concrete, concrete bricks, aerated concrete), brick ceilings, prestressed concrete hollow slabs, reinforced aerated concrete, gypsum wallboard

Installation temperatures:

Temperature of anchoring base: >= -40°C

Temperature of wall plug body: >= 0°C

The stainless steel screw can be used outdoors, in industrial atmospheres and in coastal areas

Suitable for attaching metal brackets, metal rails, suspended ceilings, cable conduits, angle brackets, profiles, etc.
