Security Door Installation Part 10: Fixed Posts and Pull Straps

Holt Renfrew Security Grille

Dynamic Closures security grilles are easy to install, but if you’ve never done it before there are some steps you will want to follow so that your door works as smoothly as possible for all users. We include the basic PDF instructions with every installation kit, but in this series of blog posts we explore a few more details and help you avoid some pitfalls you can run into if you’ve never installed a security door before.

This post is part of a longer series, so you may want to start from the beginning.

What Is a Fixed Post?

Fixed posts don’t move – they simply attach directly to a wall or other structure. They have no locks and don’t sit in pockets. Their purpose is to provide support for the grille and security for your space by connecting to a vertical surface.

Installing Fixed posts is easy.

1. First, you need to position it. Centre the post about 1.5” under the track, and check that the post is plumb.

2. Once it’s in position, use the 2” screws provided to attach the post to the wall.

If your wall or other surface is made of anything other than wood or metal, you’ll need to ensure you have the appropriate fasteners.

Pull Straps

Pull Strap Buckle

Pull straps allow door users to open and close the security grille smoothly, especially when the door is especially tall.

They come already installed in fixed posts for counter-height doors and taller-than-full-height doors. The strap fits in an adjustment buckle, somewhat like one on a ski boot.

We provide 2 different lengths, depending on your needs (straps suited to wheelchair users are available). If at some point in the future you need a new or longer strap, we can provide one.

Pull Strap Adjustments

Pull Strap Security Door1. Determine the Right Strap Length

On full-height doors, the pull strap is typically attached about 1” above the lock. On tall counters, the strap is usually allowed to hang below the lock in order to be easily grasped.

To adjust the length, open the buckle so that the strap can be moved, and find the right length. You may need to get your customers involved in this step – the right height for you may not be the right height for the staff who will be using the door.

You’ll need to position the strap so that the part with the adhesive backing won’t cover the lock.

2. Trim the Excess Strap

Once you know you have the right length, use sturdy scissors to trim the extra so it doesn’t look untidy. Make your cut below the top of the buckle, so that no one sees the rough edge.

5. Peel and Stick

Remove the backing from the underside of the strap loop, pull the strap so it’s tight, and then press it firmly into the post.

Next Steps – And Where to Find Help

At this point all of your posts will be installed, and should be working smoothly. In this next post, we’re going to talk about how to make some fine adjustments to the lock plate and the curtain height to compensate for any eccentricities in the level or squareness of the opening of your secured area.
