The Von Duprin 900594 is the OEM device template package for the 98/99 Series rim exit device. The "9899R57" suffix identifies this package as specific to the 98 and 99 Series rim configuration, providing the precise door preparation layout installers need to correctly position the device on the door before drilling. Using the wrong template, an imprecise hand-drawn layout, or no template at all is how exit devices end up mounted 1/4 inch off from the strike keeper, requiring expensive rework and field modifications that push a straightforward installation into a half-day problem.

This template package is a physical door prep tool that gets taped to the door face to mark hole centers, fastener locations, and cutout boundaries for the chassis and latch. It ensures the device sits at the correct height and lateral position relative to the door edge, which directly affects how the latch engages the strike and whether the push pad clears the door frame properly.

What the Von Duprin 98/99 Series Device Template Covers

The 98/99 Series rim exit device mounts on the inside face of the door with a surface-applied strike on the door frame or mullion. The template package marks the locations for all chassis mounting screws, the latch case position, and the fastener pattern that secures the device through the door stile. On hollow metal doors, the template provides the hole patterns for the mounting bolts that secure both the inside chassis and the outside strike. On wood doors, the template accounts for the different prep requirements at the door edge.

The 98 Series has a smooth mechanism case and the 99 Series has a grooved mechanism case. Both are non-handed and share the same rim mounting configuration, which is why this template package covers both devices in a single package. The 98/99 rim device fits all types of single and double doors with mullion and is available in 3-foot and 4-foot lengths, with the template accommodating both standard device lengths.

Why the Von Duprin 98/99 Series Gets Specified

The 98 and 99 Series are Von Duprin's flagship heavy-duty push pad exit devices, ANSI/BHMA A156.3 Grade 1 certified and UL listed as Panic Hardware (UL 305) and Fire Exit Hardware (UL 10C). They're specified on high-traffic commercial, institutional, and industrial openings where durability, code compliance, and reliable egress are non-negotiable. Hospitals, schools, universities, government buildings, and commercial offices all run 98/99 Series devices on primary egress openings. Both models are constructed to withstand constant daily activation across millions of cycles without performance degradation.

Because the 98/99 rim device installs on the door surface without a mortise pocket, the template prep is faster than mortise device installations, but precision still matters. Every hole and screw position on the template directly affects whether the device functions smoothly after installation or requires shimming and field adjustment.

Ordering the Right Von Duprin Template Package

Von Duprin publishes separate template indexes for hollow metal door applications and wood door applications. Confirm the door substrate before ordering. The hollow metal index covers standard gauge hollow metal doors, and the wood door index covers solid and hollow core wood door applications. For concealed vertical rod, surface vertical rod, and other device types, different template packages apply. This 9899R57 package is specifically for the rim configuration of the 98/99 Series.
