Uni-Sleeve Anchor
The Uni-Sleeve has a 65mm long internal thread for 15mm tie rods and is ideal for:
- single-faced formwork
- edge formwork
- scaffolding brackets
- general guard rails
Safe working load: 27 kn.
Assembly:
- The cone is nailed to the formwork with pre assembled nail.
- Push on Uni-Sleeve
- Concrete and then remove formwork
- Screw in tie rod as required
- With the special sealing groove, the sleeve closes tightly preventing concrete from entering the sleeve.

Drop in Anchor 15mm
A drop in Anchor specifically designed for the use with 15mm Formwork Tie Rod Bars. It is ideal for low load applications, such as fixings for hand rails into existing concrete. For safety reasons we state that admissible loads for a low concrete strength of 15 M/mm. This means in practice that the anchors are often installed the next day after concreting and are already loaded.

Robusta Vertical Positioner
The Robusta vertical installation kit is the perfect solution for avoiding drilling holes into concrete slabs after they have been poured to accept 15mm Dywidag thread bars.
Installation takes place prior to the slab being poured, leaving ideal anchor points for props, handrails etc after pouring.
The units consist of four main component, the body, a hollow threaded tube section, the threaded plastic plate for fixing to the reinforcement mate and the marking plug with aerial that allows the tube to be located after pouring of the slab.
