Reliable anchoring with the Fischer FIS H 12X85 K

Practical benefits

Reduced consumption of mortar: The specialized mesh structure dispenses chemical mortar evenly into masonry voids while preventing unnecessary material waste.
Secure grip overhead installation: Integrated barbs lock the sleeve securely inside the drill hole so it cannot slip out during overhead work.
Accurate centered rod positioning: Centering wings hold threaded rods of various diameters firmly in place for a balanced and stable fixing.

In a nutshell

The right choise for

With the Fischer fis h 12X85 k plastic anchor sleeve, you achieve strong and reliable chemical fixings in hollow masonry and perforated brick. The specialized mesh structure dispenses chemical injection mortar evenly into hollow chambers, preventing mortar from draining away and reducing material waste. Integrated barbs hold the sleeve firmly inside the drill hole, ensuring a secure grip during overhead installations. Additionally, practical centering wings accurately position Fischer fis a threaded rods from M6 to M8 right in the center. This gives you full control and a durable, form-locking anchor for demanding mounting jobs.

Product description

The injection anchor sleeve for particularly sparing mortar usage in perforated brick masonry.

The fischer injection anchor sleeve FIS H K is the system component for the professional, mortar-saving installation of the threaded rod FIS A or internal threaded anchor FIS E in perforated brick masonry. The fischer injection mortars FIS V, FIS VW HIGH SPEED, FIS VS LOW SPEED, FIS VL, FIS Green, FIS P Plus, and FIS P can be used with it. The optimised grating structure reduces the use of injection mortar. When the threaded rod and internal threaded anchor are installed, the mortar is pressed through the grating structure and creates a form fit with the perforated brick. This directs the load into the building material. Setting takes place in a pre-positioned installation. You can use the injection anchor sleeve to bridge non-load-bearing layers. The approvals of the various injection mortars must be observed.

Lattice structure of anchor sleeves lowers mortar consumption
Anchor sleeve allows for optimum mechanical interlock in perforated brick
The centring blades fix anchor rods with various diameters. This lowers complexity and simplifies storage
Barbed hook: no falling with overhead installations
ETA approval
The grating structure of the FIS H K anchor sleeve is adapted for the injection mortars FIS V Plus,FIS V,FIS VL, FIS Green and FIS P Plus, and ensures sparing mortar use with the best interlock
The centring blades perfectly align the anchor in the anchor sleeve, and allow for use with various threaded rod diameters
The barbed hooks secure the anchor sleeve in the drill hole and allow for a trouble-free overhead installation
The geometry of the anchor sleeves allows for the bridging of non-bearing layers for a simple and convenient installation

Suitable for

The system can be used with any of the following injection mortars:FIS V Plus, FIS VW Plus High Speed, FIS VS Plus Low Speed, FIS V, FIS VL, FIS Green or FIS P Plus. FIS P can be used but does not have approvals
The system is suitable for pre-positioned installation when combined with injection anchor sleeves and threaded rods FIS A or internal threaded anchors FIS E
The anchor sleeve is placed in the drill hole, and filled with injection mortar from the anchor sleeve base
Turning in the anchor causes the mortar to be pushed through the anchor sleeve's grating structure, so that it fits the base material perfectly. The load is borne by the interlock
