Ceiling Fan Size & Clearance
*A minimum clearance from the tip of the blades to the nearest ceiling fixture is critical to allow unrestricted airflow and to prevent unwanted noise or fan wobbling.
The PRISM+ High Security Lock was easy to install and feels much more secure than the original lock. The build quality is solid, and the locking mechanism operates smoothly. It gives me greater peace of mind knowing my mail is better protected. Overall, it's a simple but worthwhile upgrade, and I would definitely recommend it to anyone looking for a reliable replacement lock.
Clean design. Easy to use. Works well with the mobile app too. The voice volume of the unlocked and locked is very soft though. Overall it is a good and value purchase.
After install the prism+ letterbox lock.i My family's members can easily access without the key. Thumb up!
Simple and easy to use, definitely serve its purpose!
Most convenient and easy to use digital letter box lock, got it with the gate lock bundle! Thanks Prism+ for the good deal!
