Panduit PSL-1033 Electrical Panel Lockout Bar
Overview
The Panduit PSL-1033 is a polycarbonate electrical panel lockout bar designed to physically block access to circuit breaker panels — keeping unauthorized personnel away from live circuits during maintenance windows and preventing accidental equipment shutdowns on the floor. At 13 inches collapsed and expanding to 20 inches, a single PSL-1033 covers the breaker column width found on most standard residential and light commercial panels without requiring a separate sizing kit. Sold as bar-only (one unit per package), it pairs with your existing padlocks to complete a LOTO station.
This device is built specifically for lockout/tagout programs in industrial, manufacturing, and facilities environments where OSHA 29 CFR 1910.147 compliance is not optional. If your safety program is currently relying on tape, signage, or verbal procedure to protect panel access, a hardened polycarbonate bar is a meaningful upgrade to an enforceable physical control.
Key Features
- Expandable 13" to 20" coverage: The bar stretches from 13 inches collapsed to a full 20 inches extended — enough to span the breaker rows on most standard electrical panels without trimming or modification. Measure your panel face before ordering if you are working with a non-standard enclosure wider than 20 inches.
- Polycarbonate construction: Polycarbonate is impact-resistant and electrically non-conductive, which matters when workers are installing or removing the bar near live adjacent circuits. It is not a substitute for arc flash PPE, but a non-conductive barrier is the correct material choice for this application.
- Red high-visibility color: The red finish makes the lockout condition immediately visible across the room — reducing the probability that a worker or contractor misses a locked-out panel status before reaching for a breaker. Visual cues are a recognized layer of any effective LOTO program.
- OSHA 1910.147 compliant: The PSL-1033 meets the Control of Hazardous Energy standard — the federal regulation governing lockout/tagout procedures. Deploying compliant hardware is the baseline for any audit-ready safety program; non-compliant improvised devices create liability exposure.
- Panduit safety-security product line: Part of the broader Panduit safety and security catalog, this bar is engineered to work with standard padlock hasp hardware. If you are building out a full LOTO kit, Panduit offers compatible hasps, tags, and stations in the same family.
- 1" width profile: The 1-inch-wide bar (25.4mm) fits into the recessed track of standard breaker panel doors and frames without requiring modification to the enclosure. Verify the slot depth on non-standard enclosures before deploying at scale.
- Sold individually, available in case quantities: Each order ships one bar. For facilities deploying LOTO programs across multiple panels or work cells, the carton quantity is 10 units — useful for stocking a safety cage or distributing to multiple maintenance teams without piecemeal reordering.
Integration and Compatibility
The PSL-1033 is designed for use with standard electrical panels and circuit breaker enclosures. It is a passive mechanical device — no wiring, no power, no software integration required. The bar accommodates standard padlock shackles; pair it with any LOTO padlock that fits a hasp of standard diameter. For multi-worker lockout scenarios (where each authorized employee must apply their own lock), verify that your selected padlock hasp accepts multiple shackles simultaneously — the bar itself does not limit lock count.
For facilities running a documented energy control program, the PSL-1033 satisfies the hardware requirement under OSHA 1910.147 for a lockout device capable of holding the energy-isolating device in the safe position. Combine with compliant lockout tags and a written procedure to meet the full standard.

Frequently Asked Questions
Q: What panel widths does the PSL-1033 fit?
A: The PSL-1033 spans from 13 inches collapsed to 20 inches fully extended, covering the breaker column width on most standard electrical panels. Measure your panel face before purchasing if you are working with a non-standard or wide-format enclosure beyond 20 inches.
Q: Does the PSL-1033 include a padlock?
A: No. The PSL-1033 is the bar only — padlocks are sold separately. It accommodates standard LOTO padlock shackles. For multi-worker lockout, use a multi-lock hasp that accepts multiple padlocks simultaneously.
Q: Is the PSL-1033 OSHA compliant?
A: Yes. The PSL-1033 complies with OSHA 29 CFR 1910.147, the Control of Hazardous Energy standard governing lockout/tagout procedures. It is designed to function as an energy-isolating lockout device under that regulation.
Q: What material is the PSL-1033 made from?
A: The bar is constructed from polycarbonate — an impact-resistant, electrically non-conductive thermoplastic suitable for use near electrical enclosures during maintenance activities.
Q: Can I order the PSL-1033 in bulk?
A: Yes. The standard carton quantity is 10 units, making it practical to stock multiple panels or equip several maintenance teams from a single purchase. Each individual package contains one bar.
Q: Is the PSL-1033 the same as the PSL 1033?
A: Yes — PSL-1033 and PSL 1033 refer to the same Panduit part. The hyphen is part of the official model number; searches without the hyphen will return the same product.
The PSL-1033 gets specified a lot in manufacturing and utilities work because it solves a specific, recurring problem: standard electrical panels have no built-in provision for lockout, and improvised solutions (tape, zip ties, verbal warnings) do not satisfy OSHA 1910.147. The 13-to-20-inch adjustable span of the PSL-1033 means one SKU handles the column width on a large share of the standard panels you will encounter without needing to stock multiple sizes.
Technical Highlights:
- Expandable span (13" to 20"): Covers the breaker row width on most standard residential and light commercial panels without modification — one bar per panel face in the typical installation.
- Polycarbonate material: Non-conductive and impact-resistant — the correct material choice for a device that workers handle adjacent to live circuits during installation and removal.
- OSHA 1910.147 compliance: Satisfies the hardware requirement for an energy-isolating lockout device under the federal Control of Hazardous Energy standard — which is what makes the difference between a documented LOTO program and a liability gap during an OSHA inspection.
Deployment Considerations:
- This is bar-only — budget for padlocks separately, and if your procedure requires multi-worker lockout (each worker applies their own lock), spec a multi-lock hasp rated for simultaneous shackles; the bar does not include hasp hardware.
- The 20-inch maximum extension is a hard limit — non-standard wide-format panels or switchgear wider than 20 inches will need a different device. Measure panel face width before deploying at scale across a mixed panel inventory.
The PSL-1033 (often searched as PSL 1033) is well-suited for facilities maintenance programs in manufacturing plants, warehouses, and light industrial environments where routine equipment service requires repeatable, auditable panel lockout — specifically where a documented energy control program is already in place and you need compliant hardware to back it up.
