Von Duprin 7500/2: The Double Cylinder Mortise Lock Built for Exit Device Openings

The Von Duprin 7500/2 is a double cylinder mortise lock body designed to work directly with Von Duprin's 55, 88, 98, and 99 Series exit devices. The "2" in the model number means there is a key cylinder on both the inside and outside of the door, giving independent key control on each side. The exit device bar handles emergency egress at all times. The cylinders control the trim function only. If your project calls for key control from both sides of a door that also carries panic hardware, this is the correct lock body to specify. This guide explains how it works, where it belongs, and what to confirm before the order is placed.

What the 7500/2 Actually Does

The 7500 is Von Duprin's mortise lock body designed specifically for their exit device lineup. It is not a general commercial mortise lock adapted for exit device use. The geometry, latchbolt profile, and actuator cam interface are built to work with Von Duprin exit devices as a matched system.

The double cylinder configuration on the 7500/2 means both the inside and outside positions have a key cylinder. The outside cylinder controls outside trim access. The inside cylinder gives facilities personnel key control of the inside trim function without depending on the outside credential system. This is useful on doors where staff need to lock or unlock the inside trim independently, for example on a secure staff corridor in a hospital or a records room in a government facility.

The finish designation 32D refers to Satin Stainless Steel, also called US32D under ANSI finish standards. It is the most common finish on institutional and healthcare hardware because it resists corrosion, holds up under regular cleaning, and does not show wear after years of heavy use.

Where This Lock Body Gets Specified

The 7500/2 shows up most consistently on these opening types:

• Healthcare controlled corridors: Staff-only areas connecting to public egress routes, where both entry and inside trim control need to be key-managed.

• Government and institutional interior security doors: Openings where access from both sides is regulated but the door is also a required egress path and must carry rated exit hardware.

• High-security commercial interiors: Data centers, secure records rooms, and cash-handling areas where the occupancy and code provisions permit double cylinder control alongside panic egress.

• Correctional and detention facilities: Double cylinder interior doors are standard specification in these occupancies. The exit device provides the egress path regardless of cylinder position.

In all of these applications, the exit device handles egress. The 7500/2 cylinders control trim only. That is what makes the double cylinder configuration code-compatible on these doors.

What to Confirm Before Installation

The 7500 lock body is field reversible without removing it from the door. The 3/4 inch anti-friction latch bolt is also field reversible in place, which makes handing corrections straightforward on active job sites. The faceplate has an adjustable bevel that accommodates both flat and beveled door edges.

Three things to verify before installation begins:

Cylinder is not included. A 1-1/4 inch mortise cylinder with a straight cam is required for both the inside and outside positions. This is not the standard cam used in general commercial mortise applications. Order the correct cylinders at the same time as the lock body.

Function setting. The TP (thumbpiece) and K (key-only) functions are field selectable by adjusting a set screw inside the lock body. Confirm which function the hardware schedule calls for and set it before the exit device goes on the door.

Door clearance. The standard 7500 requires a minimum of 4-1/2 inches of door clearance. The SS7500 stainless and E7500 electrified versions require 4-11/16 inches minimum. Verify this against the door schedule before the hardware arrives.

7500/2 vs the E7500 Electrified Version

The standard 7500/2 is a purely mechanical lock body. No wiring, no power supply, no access control integration. It is the right choice when the exit device handles credential management through electrified trim or a separate reader, and the mortise lock body only needs to provide mechanical double cylinder control.

The E7500 is the electrified variant. It adds remote electrical control of the outside trim through an access control system or fire alarm. When the E7500 receives an unlock signal, the outside trim operates freely. The outside cylinder provides mechanical override. The E7500 is available in fail secure configuration and is used where codes permit locking but require electrical unlocking on fire alarm activation.

If the project uses electrified exit device trim for credential management and the inside also needs key control, the answer may be the standard 7500/2 paired with electrified exit device trim rather than the E7500. Confirm the access control and fire alarm integration requirements before finalizing the specification.

Compatible Exit Device Series

The Von Duprin 7500/2 is designed for use with:

55 Series and 88 Series. Classic Von Duprin exit device crossbars. The 55 is the narrow stile version. The 88 is the standard wide stile device. Both accept the 7500 mortise lock body for trim applications requiring outside cylinder access control.

98 Series and 99 Series. Von Duprin's primary heavy-duty exit device lines for commercial and institutional use. The 99 is the wide stile version. These are the most common pairing with the 7500/2 across healthcare, education, government, and institutional projects.

If the hardware schedule calls for a Von Duprin 98 or 99 Series device with mortise trim and double cylinder control, the 7500/2 is the lock body for that door.

Why Choose American Locksets

Twenty-four years in commercial door hardware is not a marketing line. It is the difference between a supplier who recognizes a model number and one who knows exactly which cylinder cam profile, which function setting, and which exit device pairing it belongs with before the question is even finished. When you are sourcing the Von Duprin 7500/2 for a controlled-access opening with exit hardware, that depth of product familiarity is not a nice-to-have. It is what keeps a hardware schedule moving.

Authorized Allegion Dealer Since 2001

Every unit of the Von Duprin 7500/2 we ship comes through official Allegion distribution with a valid manufacturer warranty and current factory documentation. Non-authorized sources carry no such guarantee. Grey-market hardware and discontinued stock look identical in a photograph and create real problems the moment a warranty claim needs to go somewhere.

Same-Day Shipping From Multiple US Warehouses

Hardware schedule delays almost never come from the job site. They come from the supply chain. We ship same day from multiple warehouse locations across the country, which means a contractor on the West Coast gets the same lead time as one in the Northeast. Free shipping applies on orders of $300 and above. Expedited options are available when a project cannot wait for standard transit.

30-Plus Brands, One Order

The 7500/2 does not ship alone on most projects. It goes alongside Von Duprin 98 or 99 Series exit devices, compatible mortise cylinders with straight cams, and often a full exit hardware package across multiple doors. We carry all of it:

• Full Von Duprin exit device lineup through our exit hardware section

• Compatible cylinders and cores through our cylinders, cores, and keys section

• Electric strikes, electronic hardware, and door closers to complete the opening

One order, one shipment, one invoice. That matters when you are coordinating delivery across a multi-door project on a schedule that does not move.
