Pemko 3572SP 80 – Frequently Asked Questions

1) Will a Pemko 3572 security bar astragal work on a pair of doors, or is it only for single doors?
The 3572 offset security bar is for single outswing doors, wood or metal. It surface mounts to the door face and covers the gap between the door and the jamb so the latch area can't be pried or manipulated. For a pair of doors, where the vulnerable gap is between the two leaves rather than at the jamb, this is the wrong part; you want a meeting stile astragal instead.
2) Can I put a Pemko 3572 security bar on a fire rated door without voiding the label?
Yes. The 3572 offset security bar meets NFPA 80 requirements for installation on fire rated doors when installed properly. That is the reason it shows up on school and healthcare corridor doors, where the opening carries a label and the security retrofit still has to happen.
3) Do I need to order a left hand or right hand version of the 3572 security bar?
No handing to specify. The 3572 is a non-handed design and works with square, bevel, and bullnose door edges, so the same bar goes on either a left or right hand opening. You only pick length and finish.
4) How does the Pemko 3572 security bar fasten to the door, and does anything need to go through the door?
It mounts to the door face with 1/4 x 20 security thru-bolts, so the door gets drilled through and the bar is bolted rather than screwed. Thru-bolting is what makes it tamper resistant from the outside, but it means you are committing to holes through the leaf, and on a hollow metal door you need access to both faces to set the bolts.
5) How much does the 3572 security bar stick out from the door face?
Projection off the face is 3/16 inch, and the bar is 2-1/4 inches wide. That low profile matters where the door swings past a wall return or an adjacent door in a vestibule, and it keeps the bar from catching carts or gurneys in a busy corridor.
6) Which finish of the Pemko 3572 should I use on an exterior door?
Three finishes are offered: satin stainless steel, galvanized steel, and black suede powder coat, and all three come in every length (80, 84, and 96 inch). Satin stainless is the one to specify for exposed exterior openings or coastal and washdown environments where corrosion is the concern. Galvanized is the plain utility choice for industrial and back-of-house doors. Black suede powder coat is the pick when the bar has to disappear against dark storefront or painted hollow metal at a school entry.
7) Will an offset security bar stop someone from shimming the latch on an outswing exterior door?
That is exactly what the 3572 is for. On an outswing door the latch and the door edge are exposed to the outside, so a shim or pry bar can reach the bolt. The bar covers the gap between the door and the jamb along the full leaf height, and being thru-bolted with 1/4 x 20 security fasteners it can't simply be unscrewed from outside. It does not replace the lock; it denies access to it.
8) Can I standardize the Pemko 3572 across a school's exterior doors?
It is built for that. The bar is non-handed, so one part number covers every opening regardless of swing, and it fits square, bevel, and bullnose door edges on both wood and metal leaves. Across a fleet you are only tracking length (80, 84, or 96 inch) and one finish. It has been approved by major school districts for use in educational facilities and meets NFPA 80 for the labeled openings in the same run.
9) What gauge steel is the Pemko 3572 offset security bar?
It is built from 7 or 10 gauge steel, with stainless steel available. That is heavy plate for a door accessory, which is the point: the bar has to resist a pry bar levered into the gap, not just cover it cosmetically.
