Pemko HG-305 7FT SS – Frequently Asked Questions

1) Will the Pemko Markar HG305 hinge guard work on a 1-3/8 inch door?
No. The HG305 is built for 1-3/4 inch door thickness only, so a 1-3/8 inch door (common on older interior openings) is outside what this guard mounts to. If your opening is 1-3/8 inches, you need a continuous hinge sized for that thickness instead. On 1-3/4 inch commercial doors, which is the standard thickness, it is a full mortise installation between the door edge and the frame.
2) What is the maximum door weight and width a Markar HG305 continuous hinge guard will carry?
600 lbs, on doors up to 4 feet 0 inches wide. That covers most single commercial leaves, including heavy lead-lined or insulated doors in healthcare corridors. Go wider than 4'0" on the leaf and you are past what the HG305 is rated to hang, regardless of weight.
3) Is the Pemko HG305 hinge guard approved for a 3-hour fire rated door assembly?
Yes. Fire ratings up to and including 3 hours, with UL 10C positive pressure certification and a Warnock Hersey listing. It is also ANSI/SDI 250.13 certified and meets ANSI/BHMA A156.26. For a facility standardizing hardware on rated openings, that set of listings is what lets the same guard go on both rated and non-rated doors.
4) What lengths does the Markar HG305 hinge guard come in for a 7 foot or 8 foot door?
Five stock lengths: 6'8", 7'0", 7'2", 8'0" and 10'0", all in satin stainless steel. The 7'0" and 7'2" cover the usual tall commercial leaf, and the 10'0" handles oversized openings or gets cut down. Custom lengths and hole patterns are also available if none of the five matches your leaf height.
5) Why put a hinge guard on a hospital door instead of just a heavier hinge?
The HG305 exists for cart and gurney traffic. On corridor doors in healthcare, the damage happens at the hinge edge, and a guard takes that abuse across the full height of the leaf while still doing the hinging work, so you are not replacing a beaten-up butt hinge and a scarred door edge every few years. It carries 600 lbs and is 304 stainless, so wash-down and disinfectant exposure is not a problem. Same reasoning applies in warehouses, schools, and loading corridors where anything on wheels hits the door.
6) How far will a door swing with a Pemko HG305 continuous hinge guard installed?
180 degrees maximum. That is enough to lay a door flat against an adjacent wall for gurney or equipment passage, but check your wall condition and any door stop before you count on the full swing. Exterior barrel diameter is .438 inches (7/16 inch), which is what sits proud in the gap between door and frame.
7) What screws come with the Markar HG305, and are the fasteners visible when the door is shut?
It ships with custom 12-24 x 11/16 inch stainless Phillips flat head undercut TEK screws, and they sit concealed once the door is closed, so nothing shows on the corridor side. If the opening is in a detention, dorm, or other area where someone will go at the hardware, tamper-proof security screws are available as an option and are worth specifying at order time rather than after install.
8) Is the HG305 hinge guard Grade 1, and will it hold up outdoors or in a corrosive area?
Grade 1, made from 304 stainless steel. The 304 alloy handles humidity, cleaning chemicals, and general weather exposure without rusting, which is why it goes into healthcare and food-handling corridors. In heavy chloride or coastal salt spray, 304 is the lower of the two common stainless grades, so plan on more frequent rinsing there.
9) Is the hole pattern on the HG305 the same top and bottom, or does it have to be ordered by handing?
The hole pattern is symmetrically templated, so the guard is not handed and one part covers left and right hand openings. That is the practical reason to stock it: a property manager or MRO shop keeps one length on the shelf instead of a left and a right. Custom hole patterns can be specified when an existing door has prep you need to pick up.
