Hager 790-903 83 US32D – Frequently Asked Questions

1) What is a half surface continuous hinge and when should I use one instead of a full mortise?
On the Hager 790-903, one leaf mortises into the frame and the other surface-mounts to the face of the door. That makes it the choice when you can prep the frame but not the door edge, or when you're hanging a door that can't take an edge mortise. It's a geared continuous hinge, so it runs the full height of the door and spreads the weight along the whole edge instead of loading three or four points.
2) Can a BEST F173 be used on a fire-rated opening in place of the Hager 790-903?
Confirm the rating before substituting. The Hager 790-903 is UL listed with fire ratings up to 3 hours on metal doors and 90 minutes on wood composite doors, and is ANSI A156.26 Grade 1 certified for 150-pound doors and Grade 2 for 300-pound doors. The BEST F173 is a steel half surface hinge with a removable pin and plain bearing in the Architectural Hinges series, rated medium duty. If the opening carries a 3-hour label, the 790-903 is the hinge that states that listing.
3) What is the difference between the Hager 790-903 continuous hinge and a BEST F173 half surface hinge?
Both mount half surface, but they are different hinge types. The Hager 790-903 is a continuous geared hinge in 14 gauge (0.075") Type 304 stainless steel running the full height of the door, with dual 6/6 nylon bearings between each knuckle and a 1/4" stainless steel pin, rated for doors up to 300 lbs and 10'-0" long. The BEST F173 is a steel half surface hinge with a removable pin and plain bearing, described as medium duty in the Architectural Hinges series. The F173 is a leaf hinge installed in a set at individual hinge locations; the 790-903 is a single full-length unit that spreads the load along the entire hinge edge.
4) What clearance does the 1/8 inch inset version need at the hinge edge?
1/8 inch (3.2 mm) minimum on the hinge side, plus your standard lockside clearance. The inset design is what buys you that tight gap. If the existing opening has a wider hinge-side gap than the door was hung with, the inset model is the wrong pick and you want a full surface or flush configuration instead.
5) What screws come with the Hager 790-903 and what do I fasten into?
Fastener sizes are called out by substrate: #10-24 x 5/8 inch stainless Dril-Kwik for a metal frame, #1/4-20 x 3/4 inch 2C Dril-Kwik for a metal door, and #1/4-14 x 1 inch 2C Type AB for a wood door. Sex bolts are an option and have to be specified at time of order, which is what you want on a wood door in an abuse-prone opening.
6) Can I run an electric strike or electrified lock through this continuous hinge?
Power transfer prep is available as an electric modification, either EPT 2 or EPT 10. That has to be called out on the order, since the prep is machined into the hinge. It gets wiring from frame to door without a surface loop.
7) What other options can I specify on this hinge for a Dutch door or a detention-type opening?
Options include sheared leaf, raised barrel (SWAGED), wide throw, security studs, and Dutch door prep (DUTCH). Security studs plus the built-in security molding are the ones to call out on an out-swinging exterior door. Wide throw is what you order when trim or a deep reveal means the door has to clear the frame face.
8) How is the Hager 790-903 built internally, and will it hold up to high traffic?
14 gauge (0.075 inch) Type 304 stainless steel leaves, a 1/4 inch (6.3 mm) diameter stainless pin, and dual 6/6 nylon bearings between every knuckle. Type 304 handles corrosion in exterior and washdown-adjacent openings. The continuous geared design is what keeps high-cycle doors from sagging, since no single knuckle carries the load.
9) For a corrosive or wash-down area, is the Hager 790-903 or the BEST F173 the better material choice?
The Hager 790-903 is built from 14 gauge (0.075") Type 304 stainless steel and supplied in US32D / 630 satin stainless finish, which is the corrosion-resistant option of the two. The BEST F173 is a steel half surface hinge. For damp, coastal, or wash-down environments, specify the stainless 790-903.
10) Does handing matter when ordering the Hager 790-903 continuous hinge?
Continuous geared hinges like the 790-903 are not handed the way butt hinges are, but the half surface configuration means one leaf lands on the door face, so the hinge is installed to suit the swing direction on site. What you do have to get right on the order is length, and any option prep such as EPT power transfer or Dutch door prep, since those are machined in.
11) What finish does the Hager 790-903 come in for matching the rest of my door hardware?
One finish only: 630 satin stainless steel, listed in the Hager spec as US32D. That's the standard commercial satin stainless that matches most lever trim, exit devices and push plates specified on institutional openings.
