Brady 148693 Lockout Rail

The Brady 148693 is a snap-on circuit breaker lockout rail designed for single-pole breakers using standard nylon cable ties. It accepts one padlock with a shackle up to 9/32 in and supports 120V AC circuits. Maintenance teams use it to isolate energy sources during service work.

Upgrade from Tie-Only Lockouts

This rail replaces improvised cable-tie-only methods by adding a dedicated padlock point and pre-loaded ID tag capability. The jump is worth it when a facility requires visible, tamper-evident lockout points that meet procedural audit requirements. It also suits teams moving from shared to personal lock assignments.

Snap-On Rail Limits

The snap-on design fits single-pole breakers with a switch tongue and standard nylon ties only; it will not mount on multi-pole or clamp-style breakers. One padlock per rail limits group lockout scenarios. The 1.01 in height, 2.69 in length and 2.7 in width envelope must clear adjacent hardware in the panel.

Questions about this item

How much space does the 148693 lockout rail need to fit on a single-pole breaker?

The rail measures 2.69 in long, 2.7 in wide and 1.01 in high, so it sits directly on the switch tongue without extra clearance.

What is the correct way to snap the rail onto the breaker, and where do people go wrong?

Align the snap-on feature with the switch tongue and press until it clicks; the common error is forcing it at an angle instead of straight on.

When should the nylon cable ties that secure the rail be replaced?

Replace the standard nylon cable ties whenever they show cracking, brittleness or loss of tension after repeated lockout cycles.
