The QS900 is a concealed transom closer. The ideal closer for double swing doors when floorsprings can't be used. A must for hospital specifications.
- Doors up to 1000mm - 150kg
- 5 year warranty
- Suitable high traffic
- 90 degree hold open or non-hold open
- Back check
For extra heavy duty doors or doors weighing in excess of 100kgs we recommend the QS8815 and QS5501 as an alternative for the standard QS5502.
