Frequently Asked Questions
- What is the purpose of the 45 degree lever on a sliding door lock?
On a sliding door, a standard straight lever can be awkward to operate when the door panel overlaps the frame. The 45 degree lever is angled so that it sits at a comfortable position relative to the door edge, making operation more ergonomic and natural when sliding the door to operate the lock. - How does the hooked bolt differ from a standard bolt on a sliding door?
A hooked bolt positively locks into the strike when thrown, mechanically capturing the bolt in the strike housing. On a sliding door, this prevents the bolt from being worked out of the strike by lateral movement or prying. A standard straight bolt on a sliding door can potentially be manipulated out of the strike more easily. - Is a cylinder included?
No. The 5541RL1SCNCYL is supplied without a cylinder. A compatible cylinder must be selected and ordered separately. Confirm the correct key profile and keying system with your locksmith before purchasing. - Is a strike included?
Yes. This model includes a fabricator mounting strike designed for installation into aluminium door frame systems during fabrication. - Is this suitable for both sliding and swing doors?
Yes. The 3540 Series is designed for both narrow stile sliding and swing doors. Confirm the door type and configuration with the installer to ensure the correct handing and strike position.
Additional Information
- The "no cylinder" configuration allows the keying system to be determined independently of the lock body - a common specification practice where the locksmith or keying system supplier sources the cylinders separately to ensure consistency with the project master key or restricted key suite.
- The 45 degree lever configuration is designed specifically for sliding door applications. Using a standard straight lever on a sliding door can result in ergonomic issues or interference with the door frame overlap.
- The fabricator mounting strike included with this model is intended for integration into aluminium door systems during fabrication. Confirm with the door manufacturer whether a retrofit strike is required for existing frames.
- The 3540 Series hooked bolt is a key distinguishing feature when comparing with standard mortice deadlocks. On sliding doors, always confirm whether a hooked or standard bolt is required for the specific strike and frame combination being used.
- Installation should be carried out by a qualified locksmith or door hardware installer familiar with the Lockwood 3540 Series.
