Congratulations! Your side folding security grille is almost completely installed (if you’re new to our series on Side Folding door installation start here).
All that remains is to do the fine adjustments to ensure your door operates as smoothly as possible. In this post, we’ll cover fine tuning locking mechanisms, and in the next post we’ll cover the posts and the curtain height adjustment.
While Dynamic Closures doors are built for easy installation and for forgiving measurement errors as much as possible, some installers may run into hiccups. This article contains a lot more detail than the basic PDF instructions to warn installers about potential gotchas. If you’re more experienced, you may want to stick to the simple step by step guide.
1. Adjusting the Height of the Lock Plate
Depending on how well the installation process goes, the lock plate on Wall Channel posts may end up higher or lower than it should be for smooth lock engagement.
As you may recall, Wall Channel posts are designed to receive a hook bolt to lock your door securely. If the lock plate isn’t at the right height, the hook bolt doesn’t fully catch behind the plate, and the door won’t be really locked.
Luckily it’s really easy to adjust the height of the plate.
- Unfasten and adjust. Using a Phillips #2 screwdriver, remove the two retaining screws in the lock plate and adjust the plate up or down as needed.
- Refasten the plate to the post. Two extra mounting holes are provided in case you need them to get proper “bite” into the aluminum.
- Test. Don’t forget to ensure the hook bolt catches fully.
It should not be necessary to drill additional holes in the plate.
2. Changing the Cylinder
It’s easy to swap out the cylinder lock provided to one that works with your current key system. This is also useful so you can change locks to keep your facility secure even if there is employee turnover.
Your new lock will need to be a 1” mortise cylinder lock of your choice. You can read detailed specifications here.
To remove the existing cylinder, follow these steps:
- On most post types, first remove the 3 retaining screws and the cover plate using a Phillips #2 screwdriver.
For Intermediate and Top and Bottom posts, you first need to unlock the post so that the lock plates retract, and you can see the set screw through the oval cutout.You may need to adjust the lock plates up or down to make the set screws accessible through the oval cutouts. You can find full instructions on how to do this in section 4, “Adjusting the Lock Rod Throw on Intermediate and Top and Bottom Posts”.
- Loosen the set screw using a 5/64 Allen key.
- Remove the lock cylinder by unscrewing in a counterclockwise direction. Tip: use a partially inserted key to make turning the cylinder easier.
To install the new cylinder, just reverse the steps above.
3. Adjusting the Lock Rod Throw on Bipart Posts
The throw is a rod that goes down into the floor socket, securing the post to the ground. You can fine-tune the depth on this rod to ensure a better fit for maximum security.
- First you’ll need to remove the retaining screw for the lock cover plate using a #2 Phillips screwdriver.
- Remove the two screws that hold the lock plate in place. Adjust the plate up if you need to shorten the throw of the bolt, and down to get more bolt into the floor socket.
- Replace the lock plate retaining screws, and then the cover plate.
Test the throw to ensure it works smoothly and engages fully with the floor socket.
4. Adjusting the Lock Rod Throw on Intermediate and Top and Bottom Posts
With Intermediate and Top and Bottom posts, adjusting the throw is the same in principle, but access is slightly different.
- You can find the lock rod components on the side of the post that is closest to the hanger stem. You’ll need to remove the side of the post to get access.
With the top lock rod you’re adjusting the position (it always travels 1.5” from unlocked to locked), but with the bottom lock rod you’re adjusting the length of throw.
While they vary in how they work, the way you adjust them is the same.
- Depress the spring loaded pins in the lock plate.
- Slide the plate up or down in ¼” intervals until the pins catch the lock plate at the right height.
- Replace the side of the post.
As always, don’t forget to test.
