Von Duprin

Von Duprin introduces the XP98/99 Rim Exit device. This revolutionary advancement, with its patented “smart latch bolt” design, raises both the security and safety capabilities for exit device openings. This unique design delivers the highest level of static load force resistance, an industry measurement for protection from abusive attack. These design advancements provide lower operational forces on both loaded and unloaded door conditions. This device is most valuable where door security has been compromised by pull-force attack or where door latching is weakened by deterioration frame conditions.

Other advantages include:

• XP function available in a Retro-fit kit for 98/99 device upgrades.

• Modern touchbar styling for heavy traffic applications.

• Designed for use on single or double doors with mullion.

• Fits doors with stile widths as narrow as 4”.

• Fluid damper that decelerates the pushpad on its return stroke eliminating most noise associated with exit device operation.

• Available in all finishes.

• Flush Mounted End Cap for aesthetic styling and robust reliability.

• Easy Upgrade for 98/99 Series Owners
