Zing 7294 Universal Lockout Device

The ZING 7294 is a universal lockout device designed to cover electrical plugs used with forklifts, cylinders, and gas systems. It supports OSHA standard 1910.147 and accommodates 120-volt to 250-volt plugs, including 15-30 amp 3P connectors. Additionally, it fits electric-driven forklift battery plugs and the starter battery negative terminal, enabling comprehensive energy isolation for multiple tools and systems on a single site. This versatility makes it suitable for maintenance teams managing hydraulic cylinder lockouts alongside electrical lockout tasks.
OMGTMD Lockout Tagout Universal Kit

The OMGTMD kit provides a four-pack of loto plug locks and a universal plug lockout solution suitable for forklifts, cylinders, and electrical plugs. Designed for OSHA compliance, the kit supports versatile lockout applications and is well-suited for facilities performing routine hydraulic cylinder maintenance where plug lockouts are needed to ensure safe energy isolation. The inclusion of multiple locks enables simultaneous, compliant lockouts on several devices, reducing downtime.
Stroke Control Kit for Hydraulic Cylinders

AMRAP HYDRAULICS’ Stroke Control Kit includes clamps in multiple thicknesses (0.75″, 1.0″, 1.25″, 1.5″) to fit cylinder rods from Ø1.5″ and up. The kit offers four varying sizes to match different hydraulic cylinder configurations, enabling quick conversion of stroke length and facilitating safe lockout and maintenance workflows. This accessory supports adjustments during servicing, helping ensure that cylinders cannot inadvertently extend during repair work.
TRADESAFE Gate Valve Lockout

TRADESAFE’s gate valve lockout device provides a rugged, industrial-grade lockout solution for 1″ to 2.5″ valve handles. Constructed from impact-resistant ABS plastic, it withstands harsh temperatures and environmental conditions. The device features an overlapping hinge design and a lock to ensure a solid lockout, with applications extending to outdoor faucets, gas valves, and forklift gas systems. It is compatible with handles up to 1-1/8″ wide and 3/4″ stems, making it versatile for various hydraulic and pneumatic valve lockouts in the field.
TRADESAFE Standard Ball Valve Lockout

TRADESAFE’s standard ball valve lockout is designed to secure 1/4″ to 1″ pipe diameters and 3-1/4″ valve handles. The device uses a single-piece, rugged construction engineered for durability in demanding environments. It enables quick installation with no extra tools, reducing downtime during maintenance on hydraulic or gas lines. The lockout helps prevent accidental valve operation by securing the valve in the OFF position during servicing.
HiLKCO 20 Pack Universal Circuit Breaker Lockout

HiLKCO offers a 20-pack of universal circuit breaker lockouts suitable for single-pole and multi-pole breakers. While primarily used for electrical energy isolation, these devices are often deployed alongside hydraulic maintenance tasks to prevent concurrent energization across control circuits and hydraulic power units. They are made of engineering-strength nylon PA, providing a durable, corrosion-resistant option for ongoing lockout needs in mixed-energy environments.
Buying Guide: Key Considerations for Hydraulic Cylinder Lockout Devices
- Compatibility: Confirm that the device fits your cylinder sizes, valve handles, or electrical plugs. Look for universal designs when multiple connections are present on a site.
- Material and durability: For industrial environments, choose impact-resistant plastics or hardened metals with corrosion resistance to withstand temperature swings and rough handling.
- OSHA and standards alignment: Ensure selections align with OSHA 1910.147 and other relevant standards for lockout/tagout programs.
- Ease of use: Quick-install designs, single-piece assemblies, and tool-free operation reduce downtime and training requirements.
- Multi-energy applications: Consider devices that cover electrical, mechanical, and valve lockouts to streamline safety workflows across diverse tasks.
- Lockout versatility: A kit with multiple locks and compatible accessories allows simultaneous lockouts on several devices, improving efficiency and compliance.
- Maintenance and storage: Opt for compact lockout kits with clear labeling and organized storage to minimize misapplication of devices.
- Training and documentation: Include user guides and color-coded systems to reinforce correct usage and audit readiness.
Choosing the right hydraulic cylinder lockout devices involves evaluating the specific configurations on a job site, including cylinder dimensions, valve types, and electrical components. A balanced approach—combining universal lockout options with task-specific tools—helps meet safety requirements while maintaining productivity across maintenance operations.
