The reviewer found it most valuable when a removable, no-drill solution was required to prevent unauthorized opening from inside - for example to secure closets, utility rooms or as a childproofing measure. The single biggest reason to buy is the solid diecasted aluminum construction combined with a keyed cylinder and three keys for controlled external access.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSturdy and Durable Double Door Lock:\u003c\/strong\u003e The diecasted solid aluminum alloy unibody delivers a reassuring feel of durability for daily use as a double door barricade.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeys Included:\u003c\/strong\u003e Three keys are supplied so the lock can be used both as an internal safety device and for controlled external access when needed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuits Knobset and Handleset:\u003c\/strong\u003e A wide range of adjustment lets the device fit most knobset configurations and some handlesets without drilling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePortable and Removable:\u003c\/strong\u003e The unit works as a temporary, no-drill lock you can add or remove as circumstances change, making it useful for renters or short-term needs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndoor and Some Outdoor Use:\u003c\/strong\u003e Designed primarily for indoor reinforcement, the cylinder and keyed function also make it useful as an additional layer of security on sheltered exterior doors.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe AST double door lock is best for homeowners or renters who need a non-permanent, visible reinforcement for double doors and French doors, where an extra keyed barricade on the inside is desirable.
