Deltana S44R4SEC 4" x 4" x 1/4" Radius Corner Hinge, Security, Steel (Pair)

The S44R4SEC carries a security stud (security/locking tab) on the leaves. When the door is closed, the tab on one leaf engages a hole in the opposing leaf, so the door cannot be pried off even if the pin is driven out. Worth noting: the pin itself is not a non-removable pin, the security comes from the interlocking tab rather than an NRP set screw.

It fits a 4 x 4 inch mortise with 1/4 inch radius corners, which is the routed corner profile most commercial hollow metal frames and factory-machined doors use. If your existing hinge pockets are square cut or use the 5/8 inch radius common on residential prehung doors, the 1/4 inch radius leaf will sit in a pocket with gaps at the corners and the screw pattern may not line up.

The security tab covers the main threat on an outswing door, a pin being driven out and the door lifted off, because the stud holds the leaves together with the door closed. If your spec sheet calls out non-removable pins by name, order a hinge listed as NRP, such as the Hager BB1168 NRP full mortise ball bearing hinge, since the S44R4SEC is not supplied with a non-removable pin.

The Orca Hardware 4014 Series is a 4" x 4" x 1/4" radius corner plain bearing commercial hinge, matching the S44R4SEC on size, corner style, and plain bearing action, without the security/locking tab option the Deltana carries. If the opening is an interior commercial door with no reverse-swing exposure, the Orca 4014 covers the same geometry.

The Deltana S44R4SEC uses a security/locking tab and is not supplied with a non-removable pin. The Hager BB1168 NRP is a full mortise ball bearing heavy duty hinge furnished with a non-removable pin, which is the usual answer when the specification calls for NRP on an out-swinging exterior door.

The S44R4SEC is a 4" x 4" hinge, so it will not drop into a 3-1/2" mortise. The Orca Hardware 3514 Series is a 3-1/2" x 3-1/2" x 1/4" radius corner plain bearing commercial hinge, which keeps the same radius corner and plain bearing action at the smaller prep.

No. The S44R4SEC is a mechanical full mortise hinge with a security tab and carries no wiring. For power transfer at the hinge, use an electrified hinge such as the Command Access ETH-CB70 energy transfer hinge, a 3-knuckle standard weight steel base unit, or the BEST CECB179-12C steel full mortise concealed bearing electrified hinge with a 12-wire quick connect. If the opening also needs door position monitoring, the Command Access ETM-CB70 adds door position sensing.

It ships as a pair, so a standard door hung on three hinges needs two packs. The ordering finish choice is Antique Brass.

Full mortise means both leaves are routed flush, one into the door edge and one into the frame rebate, so the hinge is hidden when the door is closed. The door and frame both need hinge pockets machined for a 4 x 4 leaf. If only the frame can be prepped and the door cannot, a half mortise hinge like the Hager 1129 is the alternative.

For the same 4 x 4 inch footprint with 1/4 inch radius corners and plain bearing, the Orca Hardware 4014 Series commercial hinge is the direct match minus the security feature. If your frame is square cut instead, the Orca 4040 Series is the 4 x 4 square corner plain bearing version.

The S44R4SEC is a plain bearing full mortise hinge rated for commercial use. Plain bearing relies on knuckle-to-knuckle contact, so for openings that cycle heavily or carry a closer, a bearing hinge is the usual step up: the Ives 3CB1HW is a steel heavy weight concealed bearing full mortise hinge, and the Orca 3535 Series is a 4-1/2" x 4-1/2" square corner ball bearing commercial hinge.

The S44R4SEC is a commercial full mortise plain bearing hinge with a security tab, intended for standard commercial doors rather than detention construction. Openings written for detention hardware call for products such as the BEST BB855 heavy-duty steel double weight concealed ball bearing prison hinge or the Hager 990 STEEL full surface prison hinge in 3" x 4" with a welded tip.

They are not a like-for-like swap. The S44R4SEC is a commercial-rated 4" x 4" hinge with 1/4" radius corners. The Emtek 91013 is a residential duty plain bearing pair at 3-1/2" x 3-1/2" with square corners, and the Delaney exterior residential pair is 4" x 4" with a 5/8" radius, so the corner radius does not match a 1/4" radius frame prep.

The S44R4SEC is full mortise, requiring a mortise in both door and frame. Where only one leaf can be mortised, the Hager 1129 is a half mortise plain bearing commercial hinge in 4-1/2" standard weight steel. Where neither can be mortised, the Hager 990 STEEL is a full surface prison hinge.

The hinge is steel, with a stainless steel substrate, finished in Antique Brass. Straight steel hinges are for interior and protected openings; for a coastal or heavily washed-down exterior opening, specify a non-ferrous or stainless body hinge such as the McKinney T2314 non-ferrous hinge.
