Deadbolt Locks

If you’re looking at Grade 1 deadbolt locks, then you’re looking at some of the industry’s toughest deadbolts, back by top brand names, made with quality you can be confident will work well in whatever application you require them to.

Our mission here at Buy Acccess has always been simple: we want to provide our customers with exactly what they need to either implement a proper access system, or maintain and upgrade the one that they currently have, without having to scour for parts, and without having to worry about quality, costs or stock. That’s why we’ve loaded our inventory with an unparalleled amount of locks and parts for the ANSI Grade 1 deadbolts, from trusted brands that can actually work with the system you already have.

Take for example our Medeco 11TC622 deadbolts. Solid brass and with satin chrome finishes, these locks are made tough with a deep backset, and throw hardened steel that can resist sawing or attacks from hammers and crowbars. These meet the grade 1 standard for auxiallary locks, and give deadbolt locks a whole new credibility. The Medeco patented design also provides protection against unauthorized duplication.

Additionally, if you’re simply looking for a replacement part, we offer plenty of other options that can work with your existing application. For example, we have the Schlage IRDORCOR Door coring fixture, or the Arrow D60 Exit x Blank Plate non-keyed deadbolt. These are some of the many extra products that we offer beyond full locksets designed to help implement your deadbolt lock or repair your existing broken one.

Whatever your needs are, implementing these locks can be easy for any existing access system. Generally, these grade locks are used for commercial purposes, but are not limited to any specific application. Please be sure that the products you choose work accordingly with your other equipment or existing system.

We want to make this process easy for you, which is why we also offer free shipping on all orders over $200. If for whatever reason you can’t find the parts that you need here on our site, or you don’t know exactly what you’re looking for, please don’t hesitate to contact our customer service representatives—and we’ll get you exactly what you need so that you can have peace of mind with the best deadbolt lock for your access systems. Thanks for choosing Buy Access.
