Hager 4937-US26D – Frequently Asked Questions

1) Which Hager exit devices does the 4937 extension rod kit work with?
The 4937 kit fits Hager 4500 and 4600 surface and concealed vertical rod devices, plus 4700 surface vertical rod devices. It is not for rim or mortise exit devices, since those have no vertical rods to extend.
2) I have an 8 foot door with a vertical rod exit device. Do I need an extension rod kit?
Yes. Standard vertical rod devices are built for a typical 7 foot opening, so a taller door needs added rod length between the device and the top and bottom latches. The Hager 4937 adds 36 inches (914 mm) of rod on 4500, 4600, or 4700 series vertical rod devices, and the rod can be cut down on the non-threaded end if you need less than the full 36 inches.
3) What comes in the Hager 4937 extension rod kit, or do I need to buy connectors separately?
Everything for the splice is in the box: the 36 inch extension rod, a rod connector, a rod guide, and both wood and machine screws so it can be mounted to a metal or wood door. No exit device trim is included, so if you also need outside trim, that is a separate order.
4) Can I cut the Hager 4937 extension rod shorter to fit my door height?
Yes, but only on one end. The rod is threaded on both ends, and the instruction is to cut on the non-threaded portion, leaving a threaded end intact so it still takes the rod connector. Measure the finished height first, because you cannot add the length back.
5) Do I have to order the Hager 4937 rod kit left hand or right hand?
No handing to specify. The 4937 extension rod kit is non-handed, so one kit works on either leaf of a pair or on a single door swinging either direction.
6) What finishes does the Hager 4937 extension rod kit come in, and how do I match the device already on the door?
Orderable finishes are 605 bright brass, 606 satin brass, 613 oil-rubbed bronze, 625 bright chrome, 626 satin chrome, and 630 satin stainless. Match the BHMA number stamped or specified on the existing device rather than the name, since the same finish name gets used differently between brands. The base aluminum rod itself is described as matte silver.
7) Will the Hager 4937 rod kit mount on a wood door as well as a hollow metal door?
Both. The kit ships with wood screws and machine screws, so the rod guide can be fastened to a wood door or into tapped holes in a hollow metal door. It is a commercial-duty part intended for hardware on commercial openings, not residential.
8) Does the Hager 4937 kit include the exit device or the top and bottom latches?
No. The 4937 is an accessory kit only, extending rods on a vertical rod device you already have. You get the rod, connector, guide, and screws. The exit device itself, its latches, and any outside trim are ordered separately.
9) Is the Hager 4937 extension rod steel or aluminum, and will it hold up in a damp area?
Aluminum. That keeps the added rod light so it does not load the device's top latch mechanism, and aluminum resists corrosion in areas like loading docks, pool corridors, and exterior stair towers better than bare steel.
