Folding Openers

The two standard types of folding opener give a window sash movement of 150mm (Type 110 & 112). If a greater window opening is required then an extended folding opener is available, giving sash movement of 315mm. If a smaller opening is required a shorter version is available giving a shash movement of 100mm (Type 18) which is ideally suited to Top Swing and Pivot windows.

Type 100: For high level pole operation

The operating eye remains inside of the building making it easier to operate with a pole. Hand operation is not recommended due to the geometry of the opener, there is a higher risk that fingers can become trapped.

Type 112: For low level hand operation

The operating eye and tandem bar do not interfere with the internal cill boards. The position of its operating eye gives an extended arc of operation making it ideal for hand operation.

Extended Folding Openers: For high level pole operation

The operation of extended folding openers is easiest when linked with a tandem bar. If used singularly a hand operator must be uesd. When the extended opener is closed the tandem eye drops below the level of the sash, meaning that there is a risk of fingers becoming trapped if a tandem bar or hand operator is not used.

Type 18: For low level hand operation with sash movement of 100mm

Ideally suited for use on top swing and pivot windows fitted with restrictors due to the smaller sash movement of 100mm, compared with Type 112. The folding opener will fully engage before the hinge restrictor is reached.

x = sash width - 300 (round up or down to the nearest 100mm)

 

Tandem Eyes

Pole operation of linked folding openers will require a tandem eye. The tandem eye should be fitted centrally in the case of two openers, or immediately to the side of the central opener in the case of three openers. There are three tandem eye designs dependent upon use:

260 Tandem Eye for use with Type 110 folding opener

Operated with a small boss pole operator, this is the best design to suit high level windows with a cill board.

262 Tandem Eye for use with Type 112 folding opener

Where an extended arc is required. Whilst the 112 folding opener is not ideal for pole operation, there may be applications where a tandem eye is required i.e. just out of reach. The 262 tandem eye is operated with a large boss operator.

263 Tandem Eye for use with Type 110 opener

To give an extended arc. It is operated with a small boss pole operator. If the folding opener is to be used at high level with a cill board, the required clearance must be accounted for.

 

Available in 100mm increments between 400mm and 1000mm. Other sizes available to order.
