Pemko HG-326 6FT 8IN SS – Frequently Asked Questions

1) What door weight and width will the Pemko Markar HG326 hinge guard carry?
The HG326 carries doors up to 600 lbs with a maximum door width of 4 feet 0 inches. That covers most single commercial openings, including heavy lead-lined and mineral-core fire doors. If your leaf is wider than 4'0", this is the wrong hinge for it regardless of the weight.
2) Is the Pemko HG326 hinge approved for a 3-hour fire door?
Yes. The HG326 carries UL 10C positive pressure fire ratings up to and including 3 hours, and it is Warnock Hersey listed. It is also ANSI/BHMA A156.26 Grade 1. That combination is what a life-safety inspector looks for on a continuous hinge in a rated stair or corridor opening, so it can go on assemblies rated 20 minutes through 3 hours.
3) What lengths does the HG326 come in, and do I cut it to my door height?
Five lengths are offered, all in satin stainless: 6'8", 7'0", 7'2", 8'0" and 10'0". Order the length that matches your door height rather than trimming, because the hole pattern is symmetrically templated and cutting the hinge destroys that pattern and voids the fire listing. A 6'8" leaf takes the 6'8" hinge; 7'2" and 8'0" cover tall healthcare and institutional leaves, and 10'0" handles oversized entrances.
4) How much clearance do I need between the door and frame for the Pemko HG326?
5/16 inch minimum hinge clearance is required, and the exterior barrel measures .438 inch (7/16 inch) in diameter. Check the existing gap on the hinge edge before you order: if your door is hung tighter than 5/16 inch the leaf will bind against the barrel at the start of the swing. On a retrofit that usually means the edge has to be re-machined or the door rehung.
5) Is the Pemko HG326 handed, or does one part number work on both left and right doors?
One part number covers both. The hole pattern on the HG326 is symmetrically templated, so the same hinge mounts on a left-hand or right-hand opening without ordering a hand. For a property manager standardizing a building, that means one SKU per door height rather than doubling the stock for handing.
6) What is a swing clear hinge guard and when do I need one instead of a standard continuous hinge?
A swing clear hinge like the HG326 pulls the door leaf clear of the opening when the door swings to 180 degrees, so you get the full clear width of the frame instead of losing an inch or two to the door edge. That is what you want on healthcare corridors and any opening where carts, gurneys and wheelchairs pass through and every inch of clear opening counts. The guard element also shields the hinge edge and pinch point. On a standard office or storeroom door where clear width is not tight, a plain continuous geared or pin-and-barrel hinge does the same load job without the swing clear geometry.
7) Do the mounting screws come with the Pemko HG326 or do I supply my own?
Screws are included: custom 12-24 x 11/16 stainless steel Phillips flat head undercut TEK screws for mounting to both the door and the frame. Do not substitute standard wood or machine screws, the undercut head is what lets the fastener sit flush in the templated holes. Tamper-proof security screws are available if the opening is in a detention, behavioral health or public-access location.
8) Can the HG326 hinge be unscrewed from outside when the door is closed?
No. The fasteners on the HG326 are concealed when the door is closed, so there is nothing to attack from the pull side with the door secured. For openings that need more, tamper-proof security screws are offered. Combined with 304 stainless construction and stainless end pins, that makes it usable on exterior and public-corridor doors where hinge-side attack is a concern.
9) Can one continuous hinge replace the three or four butt hinges on a sagging commercial door?
Yes, and that is the usual reason to specify one. A continuous hinge like the HG326 runs the full height of the leaf and spreads a 600 lb door's load along the entire hinge edge instead of concentrating it at three or four butt locations, which is where screw pull-out and sag start. The catch on a retrofit is prep: the existing butt mortises have to be filled and the hinge edge has to give you the 5/16 inch minimum clearance. On a rated opening, any door or frame modification has to be done per the listing, and the 3-hour UL 10C rating only holds when the hinge is installed to template.
10) Which HG326 length do I order for a 7-foot door in a 7'2" frame?
Order by the door leaf height, not the frame. A nominal 7'0" leaf takes the 7'0" hinge; the 7'2" size is there for leaves actually built to 7'2", which is common in healthcare and institutional work. Measure the leaf itself, since field-built and undercut doors often come in shorter than the nominal callout, and the hinge cannot be trimmed without losing the templated hole pattern.
11) Will the Pemko HG326 hold up on an exterior or wash-down door?
The material is 304 stainless steel with stainless steel end pins, which is the standard corrosion-resistant choice for exterior entrances, kitchens, laundries and coastal work. Satin stainless is the only finish offered, so it will not match a painted or brass-finish hinge set if you are trying to keep one look across a building. On an interior door where finish match matters more than corrosion, plan on standardizing the other openings to stainless rather than expecting a plated option here.
12) Does the Pemko HG326 let a door swing a full 180 degrees against the wall?
180 degrees is the maximum swing. Whether you actually get it depends on what is beside the opening, wall returns, adjacent frames and stops all limit swing before the hinge does. Where the wall is clear, the swing clear geometry brings the leaf out of the opening so the full frame width is usable, which is the point of specifying it on a cart-traffic corridor.
