Sized for doors measuring 43 to 48 inches wide, this device features hex key dogging to hold the latch retracted during high-traffic periods and a reversible design for either door hand. Supplied less cylinder, it lets you specify the keying system of your choice, making it a versatile solution for schools, offices, and institutional buildings.

Features

• Grade 1 rim exit device rated for heavy-duty commercial use.
• Classroom function with PTB thumbpiece trim for controlled outside access.
• Designed to fit door widths from 43 to 48 inches.
• Hex key dogging holds the latch retracted for push/pull operation.
• Reversible construction adapts to left- or right-hand doors.
• Supplied less cylinder for flexible keying options.

Functional Details

The classroom function (G) allows the outside thumbpiece trim to retract the latch when the cylinder is unlocked, granting entry without a key. When locked by key from the outside, the trim is rigid and entry is denied, while the inside push rail always releases the latch for free egress.

Arm Type Details

As a rim-mounted exit device, the 8863 installs on the surface of the door with a latch that engages a surface-mounted strike on the frame. This straightforward configuration simplifies installation and maintenance compared to concealed or mortise alternatives.

Included Components

The device ships with the exit rail assembly, PTB thumbpiece trim, mounting hardware, and rim strike. A compatible mortise or rim cylinder must be ordered separately to complete the classroom function.
