700 Series - Standard duty stops/holders

900 Series - Heavy duty stops/holders

Functions

S - Stop Only
F - Friction Stop
H - Stop/Hold

Stop only units (S function) are designed to limit the degree of door swing while providing a cushioned stop. These units are a good choice for use on labeled fire doors where hold open is prohibited.

Stop/Hold units (H function) function like stop only units with an added selective on/off hold open feature. An inconspicuous slot screw on the face of the track channel allows field engagement/disengagement of hold open. Stop/hold is recommended where non-labeled doors must be held in the open position.

Friction/Stop (F function) units provide a cushioned limiting stop and adjustable friction stay. The accessible screw on top of the slide shoe allows field adjustment of the friction. This option provides a method of holding non- labeled doors at multiple positions without readjustment. Available in 700/710 Series only.

    Keep Your Doors Steady

    Posted by Francis on Feb 8th 2024

    I wanted to share my thoughts on the Dorma 900 Series Door Stops. One thing I really like is their heavy-duty construction, ensuring durability and reliability. However, adjusting them can be a bit tricky, especially for first-timers. Overall, they're a solid choice for keeping your doors in place and adding a touch of security to your space.
