CISA Revolution Pro 56.525 Lock, Mortise, Cylinder

The Cisa Revolution Pro 56.525 lock has a cylinder pull protection system. If an intruder breaks off part of the cylinder, the entire lock automatically blocks, and further manipulation is impossible. This protection is two-sided. The lock has a reduction gear mechanism that ensures the smooth and easy operation of all its parts. Key turns are light and smooth. Thanks to this, the lock has a very large resource—200,000 locking cycles. Furthermore, the reduction gear is designed in such a way that it resists various methods of forced breaking-in. It operates very quietly. The lock is suitable for both left-hand and right-hand door opening. There is an option to install additional rods for three-way door locking, or to install deviators. The diameter of the lock bolts is 18mm. The throw length is 30mm. The lock is resistant to corrosion, so it can be installed on doors that are operated in unfavorable weather conditions.
