5 Best Lockout Kit | The Kit That Actually Works

TRADESAFE builds kits for real industrial environments — this 34-piece set includes a plug lockout and five circuit breaker locks that the simpler SAFBY kit skips.

Where basic kits give you one hasp type, this one includes two chrome-plated steel hasps with nylon-coated handles plus a non-conductive (does not carry electricity) polypropylene hasp, so you can handle both standard and electrical isolation points. It also throws in a medium-sized plug lockout for 110V to 125V plugs (a device that covers a power plug so it can’t be inserted) and five circuit breaker locks (120/277V clamp-on and universal multi-pole styles), which the SAFBY kit skips entirely.

The four padlocks are keyed different with a non-conductive thermoplastic (a type of plastic that does not conduct electricity) unibody and a corrosion-resistant stainless steel shackle (the U-shaped locking loop), plus a key-retaining brass core cylinder that prevents the key from being removed while the shackle is open — a small but important safety feature. Owners who have used it “for years with no problems” highlight the reliability, and the kit earnestly includes 20 weather-resistant PVC tags and 30 zip ties. The carrying bag is tear-resistant polyester canvas, which is more durable than the basic nylon pouch that comes with budget options.

The catch is straightforward: at 34 pieces, it has fewer total pieces than the 47-piece VEVOR kit, so if you need a massive parts count for a large crew, the VEVOR kit carries more. But for field service technicians and small electric work where the right adapter matters more than raw piece count, many find this is the one that fits.

With 47 pieces, this VEVOR kit is the highest-count option — at 47 pieces versus the TRADESAFE kit’s 34 pieces.

The extra items primarily come from three types of circuit breaker lockouts (devices that lock a breaker switch in the off position) and a plug lockout device, making it especially useful for facilities that need to secure a variety of electrical disconnects. The padlocks are non-conductive and corrosion-resistant, each engraved with matching codes on the key and lock body so you never mix up which key fits which lock.

The hasp selection covers both bases: two steel hasps with plastic-treated handles for standard use and one insulated nylon hasp for electrical environments. The review pages sum it up: “This kit puts everything my Workmen’s Comp insurance guy wants to see for Lockout.” At 3.8 lb, it is the heaviest kit in the group (at 3.8 lb versus the SAFBY kit’s 1.9 lb), but the weight comes from including more physical devices, not filler items.

The main caveat is that some owners note the keys and locks look alike and require marking to tell them apart quickly — a minor inconvenience in exchange for having a complete set. The carrying pouch is a simple bag rather than a rigid case, so organization requires a bit of personal effort. For industrial service techs who visit multiple facilities and need to be prepared for anything, this is the comprehensive choice.

At just 8.66 x 2.76 x 4.33 inches and 1.9 lb, this TAEGIQI kit is the most portable option among the larger-count kits — it slips into a service vehicle cubby or a tool bag corner.

The compact red carrying bag keeps everything — three keyed-different padlocks, three hasps, 15 tags, and 20 ties — organized in a footprint that fits in a small space. Each padlock comes with a corresponding label on the lock and key, which owners highlight as a smart detail: “each key and lock has a corresponding label on it.”

The hasp selection here is actually stronger than in some similarly priced kits. You get both steel hasps and insulated (non-conductive) nylon hasps, so the kit works for general maintenance and electrical isolation. One owner noted the “very strong lock” and that “every piece is made very strong, very heavy,” which is a good sign for a kit this small. It is ideal for electricians, HVAC teams (heating, ventilation, and air conditioning technicians), and maintenance techs who move between job sites frequently.

The minor downside is that the kit does not include any specialized circuit breaker or plug lockout adapters. That makes it a pure lockout kit rather than an all-encompassing industrial solution. But if you value easy portability and a lean, functional setup, this one hits the mark.

Master Lock is a household name in padlocks, and this kit comes in an ultra-durable safety carrying case that measures 8 x 5-1/4 x 15-1/2 inches — a rigid box that keeps every piece in its place.

Instead of a soft bag, the rigid case makes it easy to see if something is missing at a glance. Owners describe it as “spacious” and note you can expand the kit with your own specialty items over time. This is a clear advantage over the soft pouch of the SAFBY kit when organization is your priority.

The padlock lineup includes three 410RED Zenex keyed-alike padlocks (one key opens all three) with a non-conductive thermoplastic body, one 7C5RED padlock, two lockout hasps (a standard 420 and a snap-on 427), plus three grip-tight breaker lockouts, one wall switch lockout, and a pack of 12 “Danger Do Not Operate” tags. Customer consensus is that this kit “has just about everything for basic Lock out Tag out” and is a solid starter set for ensuring OSHA compliance (meeting the Occupational Safety and Health Administration’s safety rules).

The catch here is that the three main padlocks are keyed alike (one key opens all three), which is less secure for a group lockout procedure where each worker needs their own unique key — unlike the keyed-different locks in the SAFBY or TRADESAFE kits. The kit’s functionality scores as mixed in the customer data. For electricians and facility teams who prefer a rigid case and a recognized brand name, this kit holds its value — but the keyed-alike locks mean it is best for single-user or supervisor scenarios rather than full crew lockouts.
