Anti-Tip Linkage Arm

Anti-Tip Linkage Arm For File Cabinet Safety

Anti-Tip Linkage Arm describes this CompX Timberline Lock component used in anti-tip systems that prevent more than one drawer from being opened at a time, which reduces the chance of a loaded file cabinet tipping forward during normal use.

This linkage arm is part of the CompX Timberline Lock anti-tip system for file cabinets where no lock is present, so it supports applications that rely on mechanical anti-tip function instead of key control when setting up storage in offices or shops.

The arm carries manufacturer part number SN-410 and sits in the Anti-Tip Systems class under Locks and Latches, which helps match it to other CompX Timberline system parts when planning or servicing a multi-drawer installation.

The system meets BIFMA standards for strength and durability, so the linkage arm is designed to perform within recognized furniture industry criteria, which matters when specifying hardware for commercial environments that expect repeatable performance under daily drawer use.

The linkage arm works with a lockbar that can be cut to size by the user, allowing the anti-tip assembly to follow specific cabinet heights or custom casework dimensions on site without needing a different part number for each cabinet size.

Key Anti-Tip Linkage Arm Details For Buyers

• The CompX Timberline Lock Anti-Tip Linkage Arm is used on file cabinets where no lock is present, so it provides anti-tip control through the linkage system itself when drawers are opened in normal filing workflows.
• The system prevents more than one drawer from being opened at a time, which limits how much weight can shift forward at once and helps keep tall or fully loaded cabinets stable in everyday operation.
• All components in this anti-tip system are surface mounted, which keeps installation work on the cabinet faces and sides instead of buried construction, helping installers retrofit existing file cabinets more predictably.
• BIFMA standards for strength and durability are met by the system, so the linkage arm participates in a tested assembly that aligns with typical commercial furniture performance expectations in office environments.
• The anti-tip system needs 1/2 inch drawer slide clearance, so the linkage arm works within that space and allows installers to plan slide positioning and cabinet side spacing around a known clearance value.
• The system uses a lockbar that can be cut to size by the user, which means the linkage arm can connect to a bar tailored to the specific cabinet height, supporting consistent anti-tip action across different case sizes.

Installation Fit And Drawer Clearance Details

This anti-tip system requires 1/2 inch drawer slide clearance, so the linkage arm operates alongside the slides within that margin, letting cabinet builders and installers align drawer members and side panels around a defined space for the mechanism.

All components for this CompX Timberline anti-tip assembly are surface mounted, which positions the linkage arm and related pieces on accessible cabinet surfaces, allowing installers to locate and fasten parts using standard layout methods on file cabinet sides and drawers.

The lockbar that works with this linkage arm can be cut to size by the user, which allows the bar length to follow the actual cabinet height during installation and lets the linkage arm engage correctly with bar travel over the full stack of drawers.

For a 3-4 drawer application, the system layout calls for one linkage arm per each Anti-Tip Snapper with Wurth number TLSN410, so each snapper position gains a dedicated arm that transmits drawer movement to the cut-to-length lockbar.

Where This Anti-Tip Linkage Arm Fits In Systems

Anti-Tip Linkage Arm Use On File Cabinets

The Anti-Tip Linkage Arm is designed for use on file cabinets in installations where no lock is present, so it allows builders to deliver anti-tip protection mechanically even when keyed security is not part of the cabinet specification.

This arm operates within an anti-tip system that prevents more than one drawer from being opened at a time, turning individual drawer motion into controlled lockbar movement so only one drawer can extend, which stabilizes cabinets loaded with files.

The product sits in the Anti-Tip Systems category under Locks and Latches, so it serves as one functional member of a larger assembly that includes a lockbar and other components selected specifically to manage drawer sequencing in multi-drawer units.

When a file cabinet is outfitted with this linkage arm and its related parts, the anti-tip system responds to drawer activity by coordinating movement across the stack, directing force into the lockbar instead of allowing multiple drawers to pull forward simultaneously.

Because the lockbar may be cut to size by the user, the same SN-410 linkage arm can work across cabinets of different heights, as long as the bar is cut to match the specific case, which supports consistent function across varying file cabinet runs.

Details That Support Reliable Anti-Tip Performance

The CompX Timberline anti-tip system featuring this linkage arm meets BIFMA standards for strength and durability, which means the arm contributes to an assembly built to withstand the kind of drawer cycling and static loads found in typical furniture environments.

All components are surface mounted, so the linkage arm and its mates are installed directly onto cabinet and drawer surfaces, helping maintain clear access for adjustment or service work and reducing disruption to the basic cabinet structure once the layout is set.

The system relies on a consistent 1/2 inch drawer slide clearance, and the linkage arm functions in that defined space, which simplifies layout because installers can plan slide positions and side clearances around that requirement rather than compensating for unknown tolerances.

In a 3-4 drawer application, this linkage arm is specified as one per each Anti-Tip Snapper with Wurth number TLSN410, meaning each snapper gains a dedicated arm to actuate the cut-to-length lockbar, supporting predictable drawer-to-lockbar interaction on every level.

Additional referenced parts for 3-4 drawer applications use specific Wurth numbers, such as TLSN400 for Anti-Tip Snapper, TLDC400 for one Drawer Clip per each drawer, TLLB240 or TLLB360 for the lockbar lengths, and TLAP037 for two Adjustable Pins per application, giving installers a clear bill of related system components.

By tying drawer motion through the SN-410 linkage arm into a correctly sized lockbar and related pieces, the anti-tip system coordinates drawer operation so file cabinets in offices, archives, or shops gain controlled, single-drawer extension that supports day-to-day stability when loaded.
