How to Install the Crescent Lock and How to Adjust the Front And Back Position?

Crescent lock is a common door and window hardware accessory, widely used in homes, offices and other places. So, what does the crescent lock consist of? The crescent lock is mainly composed of a door handle (left and right), a crescent lock seat, a crescent lock buckle (left and right), and small accessories such as gaskets and fixings as auxiliary. The crescent lock not only has a beautiful appearance, but also effectively improves the safety and sealing of doors and windows. However, difficulties are often encountered when installing and adjusting the crescent lock. The following editor will introduce the installation steps of the crescent lock and how to adjust the front and back position in detail.

1. Installation steps of crescent lock

Preparation: Before installing the crescent lock, you need to prepare the following tools and materials: crescent lock set, electric drill, screwdriver, tape measure, pencil, make sure the surface of the door and window is clean and flat, and check whether the size of the lock body and lock buckle matches the door and window.

Determine the installation position: Use a tape measure to measure the width and height of the door and window to determine the installation position of the crescent lock. Usually, the crescent lock is installed in the middle of the door and window, about 10-15 cm away from the edge. Use a pencil to mark the installation position of the lock body and the lock buckle on the door and window to ensure that the two are aligned.

Drill holes to fix the lock body: Use an electric drill to drill holes on the door and window according to the marked position. Note that the depth of the drilling should match the length of the screw to avoid being too deep or too shallow. Align the lock body of the crescent lock with the drilling position, tighten the screws with a screwdriver, and ensure that the lock body is firmly fixed.

Install the lock buckle: Mark the position of the lock buckle on the door and window frame to ensure that the lock buckle is aligned with the bite part of the lock body. After drilling with an electric drill, fix the lock buckle on the door and window frame and tighten the screws with a screwdriver.

Check the installation effect: After the installation is completed, open and close the doors and windows repeatedly to check whether the crescent lock bites smoothly. If you find that it is stuck or loose, you need to readjust the position of the lock body or lock buckle.

2. How to adjust the front and rear positions of the crescent lock

In actual use, the crescent lock may have a mismatch in the front and rear positions, resulting in the lock body and lock buckle not being able to bite normally. The following is a specific method to adjust the front and rear positions:

Check the cause of the problem: If the lock body and the lock buckle cannot be aligned, it may be due to the offset of the installation position or the deformation of the door and window. Use a tape measure to measure the distance between the lock body and the lock buckle to determine the direction and amplitude of the adjustment.

Adjust the lock body position: Loosen the fixing screws of the lock body and move the lock body forward or backward to align it with the lock buckle. Pay attention to keep the lock body level during adjustment to avoid tilting. After adjusting in place, retighten the screws to ensure that the lock body is stable.

Adjust the lock buckle position: If the lock body position still cannot be aligned after adjustment, you can try to adjust the position of the lock buckle. Loosen the fixing screws of the lock buckle and move it forward or backward until it is fully engaged with the lock body. After the adjustment is completed, tighten the screws and test the switch effect of the lock.

Test and fine-tune: After adjusting the front and rear positions, repeatedly open and close the doors and windows to check whether the lock is engaged smoothly. If there is still a jam or looseness, fine-tune it until the best effect is achieved.
