Dynamic Closures side folding security grilles are made to precise measurements and are easy to install for experienced contractors. But even the best-made spaces can have minor imperfections that don’t become noticeable until you start installing the door.
Changing the overall curtain height is done by adjusting the trolleys that connect the curtains to the overhead track.
Our adjustable curtain hangers help you deal with floors or counters that aren’t perfectly level , or even small errors in the measurements. This will help your door look perfectly tailored for the opening of the area you’re securing.
Not all of our customers ask for these adjustable trolleys. But if you want to be able to fine tune the size of the gap below the curtain, the extra 1” of adjustability means a lot to those who notice details like this.

How to Adjust the Curtain
Please note that you have to adjust all the trolleys to the same height or the curtain will not ride smoothly in the track. The maximum height adjustment you can make is 1” up or down.
Adjust the Trolleys
Adjusting each trolley is easy:
1. Loosen the Set Screw on the Trolley
Using the 5/64 hex key provided with your delivery, loosen the set screw just enough that the trolley shaft is freed.
2. Adjust the Shaft Height
Insert the hex key into the hole in the trolley shaft.
- Turn the hex key clockwise to raise the curtain.
- Turn the hex key counterclockwise to lower the curtain.
Count the number of turns. This will allow you to easily repeat the process.
- 8 complete rotations will make a ¼” inch change in height.
- 32 complete rotations will make a 1” change.
3. Tighten the Set Screw
Ensure the set screw is snug to retain your settings.
4. Repeat on All Trolleys
Once you know the number of turns to make on your first trolley to get the height you want, it’s easier to adjust the rest of them.
Adjust the Height of All Posts in the Curtain
1. Remove the Screws
Remove the two screws holding the hanger in place. Be sure to support the post so it doesn’t fall.
Using the ¼” index marks on the side of the hanger as a guide, adjust the post to the desired height.
3. Replace the Screws
Replace the screws, selecting appropriate holes in the hanger so that both will be able to grab the back of the support.
Test the Curtain
Your curtain should ride smoothly in the track and not drag on the ground. If needed, readjust.
We test every curtain before it leaves the factory, and one of the things we check for is smooth operation. If your curtain is snagging, then something is wrong.
