LCN 4040XP-3077 Regular Door Closer Arm (REGARM) is a factory-designated replacement arm for compatible LCN 4040XP Series heavy-duty surface-mounted hydraulic door closers. This non-handed, non-hold-open arm assembly links the closer to the appropriate door or frame attachment, allowing the installed hydraulic closer to control door movement. Replace a worn, bent or damaged arm without automatically replacing the complete closer body.

The standard REGARM supports hinge-side (pull-side) mounting and top-jamb (push-side) mounting with a shallow frame reveal, subject to the LCN template. Parallel-arm mounting requires the separately specified LCN 4040XP-62PA shoe. This product is the regular arm assembly only, not a complete hydraulic door closer or an automatic door operator.

Key Features

• Genuine LCN factory designation: Part number 4040XP-3077, Regular Arm (REGARM).
• 4040XP Series compatibility: Intended for appropriately installed LCN 4040XP surface closer bodies; confirm existing model and mounting geometry.
• Non-handed design: Suitable for approved left-hand or right-hand door configurations using the correct installation instructions.
• Non-hold-open function: Standard arm without a mechanical hold-open detent, allowing the properly adjusted closer to return the door toward the latched position.
• Regular mounting: Works with appropriate hinge/pull-side door closer installations.
• Top-jamb mounting: Compatible with specified top-jamb installations having a shallow frame reveal.
• Parallel-arm conversion: Requires compatible LCN 4040XP-62PA parallel-arm shoe; confirm the necessary shoe/bracket and installation plate.
• Commercial replacement: Service an existing heavy-duty door closer while retaining its working cylinder, cover and hydraulic components.
• Building applications: Suitable for compatible commercial office, retail, industrial, healthcare, educational and institutional openings.

Technical Specifications

Mounting Options and Door Preparation

Important: Selecting an arm solely from its appearance can lead to incorrect door geometry or poor closing performance. Check the existing closer part number, door width, frame reveal, arm linkage, special shoe and any associated mounting plate before ordering. A deeper reveal may need a long or extra-long arm rather than the standard REGARM.

Compare Other LCN 4040XP Arm Configurations

• 4040XP-3077 REGARM: Standard non-hold-open arm for pull-side and shallow-reveal top-jamb mounting.
• 4040XP-3077L LONG: Long rod-and-shoe arm for specified top-jamb arrangements needing additional reach.
• 4040XP-3077ELR XLONG: Extra-long rod-and-shoe arm for deep-reveal top-jamb mounting.
• 4040XP-3049 Hold-Open: Different arm with a mechanical hold-open function; not supplied as the REGARM.
• 4040XP-3077EDA Extra Duty: Separate extra-duty arm designed for applications with more demanding abuse resistance.

These are distinct manufacturer configurations. Do not substitute a hold-open or stop arm for standard REGARM without the approved hardware schedule. At fire-rated openings, follow the complete door assembly listing and applicable automatic closing requirements.

Installer and Facility Maintenance Checklist

1. Identify the closer: Confirm an LCN 4040XP Series body and that the standard regular arm, rather than a shoe, spindle or hydraulic cylinder, needs replacement.
2. Check the mounting: Determine whether the closer is hinge-side, top-jamb or parallel-arm mounted. Measure frame reveal and inspect arm/shoe clearance.
3. Confirm component compatibility: Compare factory arm part numbers, spindle engagement, rod, shoe, arm screw, optional plates and required frame reinforcement.
4. Order additional hardware if needed: For parallel-arm mounting, verify the 4040XP-62PA shoe. Confirm which fasteners and accessories are already present and which must be purchased separately.
5. Install from the manufacturer's template: Position the arm and shoe correctly and use appropriate fasteners; do not guess factory adjustments or arm pre-load.
6. Test full door swing: Check for loose linkage, binding, frame interference, abnormal stress and secure attachment through the usable opening range.
7. Check closer operation: Verify sweep, latch and backcheck adjustments using LCN instructions. Those hydraulic controls are located on the existing closer body, not the replacement arm.
8. Verify safety and code compliance: Confirm reliable door closing and latching, free egress, accessibility and applicable fire-door requirements.

Applications

Replacement and maintenance of compatible LCN 4040XP arms in schools, universities, healthcare facilities, assisted-living properties, retail stores, offices, warehouses, airports, shopping centers and public/government buildings. A correct factory arm helps restore consistent mechanical linkage without replacing a sound closer body.
