Pemko HG-3505 6FT 8IN SS – Frequently Asked Questions

1) Will a Pemko Markar HG3505 hinge guard work on a fire-rated door assembly?
Fire rated up to and including 3 hours, with UL 10C positive pressure certification. That covers most fire-rated openings in healthcare and institutional corridors. It also meets ANSI/BHMA A156.26 as a Grade 1 product, so it holds up on the code side as well as the durability side.
2) What size doors will the HG3505 security hinge guard handle?
The HG3505 supports doors weighing up to 900 lbs and up to 4'0" wide. Lengths are stocked at 6'8", 7'0", 7'2", 8'0" and 10'0", so standard 6'8" and 7'0" openings and taller institutional doors are both covered. Custom lengths and hole patterns are available if your opening falls outside those.
3) Do I have to specify handing when ordering a Markar HG3505?
Handing is required on the 6'8" and 7'2" lengths. The other lengths are symmetrically templated, so the hole pattern reads the same either way. Get the hand right on those two sizes before you order, because a mis-handed guard will not line up with the mortise prep.
4) How does a hinge guard mount, and does it need a separate hinge?
The HG3505 is a full mortise mounting product, installed into the hinge edge prep the way a continuous hinge is. It is a protective guard for the hinge edge rather than a decorative wrap, and it carries a 900 lb load rating with stainless steel end pins and hospital tips as standard. Custom #12-24 x 7/16" PFHMS fasteners come in the box.
5) How much clearance does the HG3505 need on the hinge side?
Minimum hinge clearance is 5/16 inch, and the door can swing to a full 180 degrees. If your frame or an adjacent wall return leaves you less than 5/16 inch on the hinge edge, the guard will bind before the door is fully open.
6) Will cart and gurney traffic tear up a hinge guard like this?
That traffic is exactly what the HG3505 is built for. It protects the door from dings and gouges caused by carts and gurneys, and the body is 304 stainless steel, which is why it holds up to wash-down and cleaning chemicals in hospital corridors. Same reasoning applies to school corridors and warehouse dock doors.
7) Can the mounting screws on a Pemko HG3505 be attacked from outside the door?
No mounting fasteners are exposed when the door is closed, so there is nothing to get a driver on from the secure side with the door shut. Tamper-proof security screws are available as well if the opening calls for them, which is the usual specification on detention, records rooms and behavioral health doors.
8) I need a 10 foot hinge guard for a tall warehouse door. Does Pemko make one that long?
Yes, the HG3505 is stocked in a 10'0" length in satin stainless steel, alongside 8'0", 7'2", 7'0" and 6'8". At 10 feet you are still inside the 900 lb and 4'0" width limits, so verify your door leaf weight against that number before you order.
