1000mm TANDEM BAR NO CENTRE HOLE
Tandem bars range in length from 200mm to 4000mm depending on the width of the window. When using tandem bars it is important to follow the tandem bar rule rules shown.
- Folding openers must be positioned between 100mm and 200mm from the corner of the sash. The tandem bar, therefore, should be 200mm to 400mm less than the width of the window.
- Tandem bar lengths are always specified by hole centers and not overall length.
- The maximum distance between linked folding openers should not exceed 900mm. If a 1000mm length tandem bar is required then a third folding opener must be used.
- If a possible length of tandem bars should be rounded up or down to the nearest 50mm increment (i.e. 550,600....850....etc.)
- When a third folding opener is used a tandem bar with a center hole can be supplied. A modified end cap 25064/M is also required.
- If a fourth folding opener is required a tandem bar will be supplied with no center holes for the inner two folding openers. Two modified end caps 25064/M will be needed.
