The single biggest reason to consider this deadbolt is its double cylinder design, which requires a key on both sides and provides consistent control over entry and exit-ideal where glass near the door or shared interior spaces make thumb-turns unsuitable. The pack of four keyed-alike locks also simplifies management for multi-door installs.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble Cylinder:\u003c\/strong\u003e Requires a key to unlock from both sides, adding a layer of security where a thumb-turn could be compromised.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Latch:\u003c\/strong\u003e Fits doors 1-3\/8 in to 1-3\/4 in thick and supports 2-3\/8 in or 2-3\/4 in backset, so it accommodates most standard door preps.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyed Alike Convenience:\u003c\/strong\u003e All four locks arrive keyed alike, reducing the number of keys needed for multiple doors and simplifying access control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign Compatibility:\u003c\/strong\u003e Available finishes are intended to blend with common decor and standard preps for a near-seamless retrofit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDIY Friendly Installation:\u003c\/strong\u003e Includes hardware and clear instructions so a competent homeowner can install the deadbolts without special tools.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe Probrico double cylinder deadbolt is aimed at homeowners, landlords, and small business owners who need controlled access on exterior doors or interior rooms where a thumb-turn is undesirable.
