The DORMA SIS 689 Spring Stop IS Arm is a heavy-duty commercial door closer arm with an integral spring-assisted dead-stop function. Designed for regular-arm and top-jamb installations with a 0"–3-1/2" frame reveal, it is used with compatible DORMA 7000 and 8000 Series surface-applied door closers. The 689 Aluminum Painted finish coordinates with common commercial door hardware.

The spring stop mechanism is intended to provide a controlled, resilient stopping action as the door reaches its selected opening limit, helping protect the opening in applications that require an integral arm stop. The arm is non-handed and available for appropriate left-hand and right-hand door installations. The SIS is the non-hold-open version; it does not latch the door in an open position.

Key Features and Benefits

• Spring-assisted dead stop: Integrated spring stop function for regular and top-jamb applications.
• Selectable stop positions: Designed for installation at 85°, 90°, 100°, or 110°, depending on the manufacturer template, door geometry, and conditions.
• 0"–3-1/2" reveal: Fits the manufacturer's specified reveal range for the SIS complete arm.
• Non-hold-open: Allows the correctly adjusted door closer to return the door toward the closed position rather than mechanically holding it open.
• Non-handed: For compatible left-hand and right-hand openings.
• Commercial-duty replacement: Ideal for repair, replacement, or new installations calling for a Spring Stop IS arm.
• Architectural finish: 689 Aluminum Painted finish.

Before ordering, confirm the installed closer model, door and frame construction, frame reveal, clearance, intended stop position, and applicable DORMA installation template. The arm's spring stop must be properly installed and adjusted to suit the opening. Check whether a separate overhead stop is required by the application; arm-mounted stops do not automatically replace every other door protection requirement.

Model & Configuration Buying Guide

Product: DORMA SIS 689 Spring Stop IS Door Closer Arm – Regular / Top Jamb | Aluminum Painted. Manufacturer/distributor designation: dormakaba / DORMA. This product is part of the Door Closer Arm category and should be selected by its actual factory ordering code, intended application and installed door hardware. Use the exact SKU when placing a replacement or construction order.

Available SKUs and Configurations

The arm assembly must match the exact closer model, mounting location, door swing, frame reveal, and opening angle. A regular or top-jamb arm is not a substitute for a parallel arm or a stop/track arrangement. The model in this listing is an arm or arm kit; a complete hydraulic closer body is not included unless the existing description explicitly specifies otherwise.

Model-Specific Features

Check whether this model provides hold-open, non-hold-open, spring stop, cushioned Door Saver, plunger, or track operation. Use the exact product title and SKU when matching the existing arm to the door hardware schedule; physical mounting dimensions and compatible closer body series differ by arm family.

Installer and Replacement Checklist

1. Identify the existing closer body and confirm the named compatible 7000/8000, HD8000, or EHD9000 series as applicable.
2. Measure reveal and top-rail/soffit clearances; identify push-side vs pull-side mounting.
3. Check required fasteners, arm shoe, bracket, parallel plate, spindle/shaft and stop components before ordering.
4. Observe opening-angle limits and available frame clearance; confirm backcheck and door stop requirements for heavy-traffic doors.
5. Verify mechanical hold-open is permitted at the opening; fire-rated doors may require an approved automatic-release arrangement.
6. Retain a compatible closer's hydraulic adjustment schedule and follow current manufacturer installation instructions.
