Sargent & Greenleaf 951-009 – Frequently Asked Questions

1) What applications is the Sargent & Greenleaf Heavy Duty Padlock designed for?
This padlock is built for high-security commercial and industrial applications. Common uses include securing gates, storage containers, utility boxes, and equipment trailers. The heavy-duty construction resists cutting, drilling, and prying attempts.
2) What shackle sizes are available for this padlock?
Available shackle configurations vary by model. Standard options include 1/4", 5/16", and 3/8" diameter shackles with various lengths. Verify your hasp or mounting hardware clearance requirements before ordering.
3) Is this padlock rekeyable or available keyed alike?
Most Sargent & Greenleaf heavy duty padlocks can be ordered keyed alike or keyed different. Some models offer rekeyable cylinders for field key changes. Contact us for specific keying options and multiple padlock orders.
4) What finish options provide the best corrosion resistance?
Stainless steel models offer maximum corrosion resistance for marine and chemical environments. Chrome-plated and zinc-plated finishes provide good protection for most outdoor applications. Black oxide finishes work well for indoor use.
5) What security rating does this padlock meet?
Sargent & Greenleaf heavy duty padlocks typically meet or exceed Grade 1 commercial security standards. Many models are tested for pick resistance, drill resistance, and physical attack methods. Check specific model documentation for detailed security ratings.
6) Can I get this padlock with a master key system?
Yes, most models support master keying for facilities requiring multiple access levels. This allows individual keys for each padlock plus master keys for supervisors. Consult with our team for complex keying requirements.
7) What tools are needed for installation?
Installation typically requires only insertion through mounting hasps or hardware. For permanent mounting applications, you may need appropriate fasteners and drilling tools based on your specific mounting surface and hasp requirements.
8) How do I maintain this padlock for maximum lifespan?
Apply graphite lubricant to the keyway periodically. Avoid oil-based lubricants which attract dirt. Clean exterior surfaces regularly in harsh environments. Cycle the lock monthly if not used frequently to prevent internal buildup.
9) Are replacement cylinders available for this padlock?
Replacement cylinders are available for most Sargent & Greenleaf heavy duty padlock models. This allows key changes without replacing the entire padlock body. Verify your specific model number when ordering replacement components.
10) What other Sargent & Greenleaf security products work with this padlock?
Sargent & Greenleaf offers compatible hasps, mounting hardware, and other Sargent & Greenleaf security products. Consider their door locks and access control systems for comprehensive security solutions.
11) Will this padlock perform in extreme weather conditions?
Heavy duty models are designed for outdoor use in temperature ranges from -40°F to 150°F. Stainless steel versions handle salt spray and humidity better than plated finishes. Consider protective covers for extreme environments.
12) How do I measure for proper shackle clearance?
Measure the thickness of materials the shackle must pass through plus any washers or spacers. Add 1/8" minimum clearance for proper operation. Measure the required shackle opening width to ensure proper fit through your hasp or mounting points.
