The Master Lock No. 3KA is a commercial-grade laminated steel padlock supplied pre-keyed to key number 3634. Every 3KA-3634 lock opens with that same key, so a gate, a fence line or a run of storefront doors can all be secured on one key - and you can add locks later to match any Master Lock hardware already running the W1 cylinder. Two keys are supplied with each padlock.

• Keyed alike to key number 3634 - order additional locks to open on the same key, or to match other locks using the W1 cylinder
• Commercial grade padlock with superior protection from drilling and prying
• 1-9/16" (40 mm) wide reinforced laminated steel body for superior strength
• Hardened steel shackle for superior cut resistance: 3/4" (19 mm) tall, 9/32" (7 mm) diameter, 5/8" (16 mm) horizontal clearance
• Dual ball bearing locking for maximum pry resistance
• 4-pin W1 cylinder helps prevent picking; the cylinder is non-rekeyable
• Weather resistant - suited to security gates and fences, industrial and storefront gates, tool cribs and vending machines
• Gray finish, boxed, two keys included
• Manufacturer part: 3KA 3634
