Imperial USA IMPTH1100-ZCX2DU – Frequently Asked Questions

1) Will the Imperial USA TH1100 mortise cylinder work with an Adams Rite storefront lock?
The TH1100 zinc mortise cylinder is threaded to screw into a mortise lock body, and the description calls out a high level of security when used with an Adams Rite (A/R) cam. That is the usual storefront setup: the cylinder body is standard mortise thread, and the cam is what has to match the lock you are putting it into. Cylinder diameter is 1-5/32 inches with a 1 inch keyway length.
2) Is the TH1100 mortise cylinder a Schlage C keyway, and can my locksmith key it to my existing Schlage keys?
Schlage "C" keyway, 5 pin. That is the most common commercial keyway in North America, so if your building is already on Schlage C, these cylinders take the same key blanks and a locksmith can pin them to your existing key. Two keys ship with each cylinder.
3) What does keyed alike mean when ordering these Imperial USA mortise cylinders for several doors?
Keyed alike means every cylinder in the order opens with the same key. Order all the doors in the group together and one key runs the set, which is what you want for a tenant suite, a storefront pair, or a run of back-of-house doors on one keyring. If you need each door to have its own separate key, keyed alike is the wrong option.
4) Is the TH1100 a double cylinder, and do I get keyed access from both sides?
It is a double cylinder setup, meaning key operation on both faces of the door rather than a key outside and a thumbturn inside. On a glass storefront entry that is common practice for after-hours security, but be aware some occupancies restrict key-both-sides on an egress door, so check what your local authority allows for that opening before you commit to double cylinder.
5) Can I replace just the cylinder in my storefront lock instead of the whole lock?
Usually yes. A mortise cylinder is a swap-out part: back out the set screw in the lock edge, unscrew the old cylinder, thread this one in and set it so the cam lands where the lock expects it. You are not touching the lock body or the door prep. What has to match is the thread and the cam, and the TH1100 is a standard 1-5/32 inch diameter mortise cylinder with an Adams Rite cam application called out.
6) What finishes does the Imperial USA TH1100 mortise cylinder come in?
Two: DU Duranodic (dark bronze anodized) and AL Aluminum. Those are the two finishes storefront doors are normally built in, so pick the one that matches the existing door frame and the other hardware on the opening. The 5/16 inch stamped trim ring included with each cylinder comes in the matching finish, so the ring will not clash.
7) Do I need to order a trim ring or collar separately with this mortise cylinder?
No, a 5/16 inch stamped trim ring in the matching finish is included, and the cylinder ships as a complete set with two keys. The ring is what takes up the gap between the cylinder face and the door or lock face, so on a normal storefront install you have what you need in the box. What you may still need is the correct cam for your lock body.
8) What is the difference between a mortise cylinder like the TH1100 and a rim cylinder?
A mortise cylinder threads into the lock body and drives it with a cam, which is how the TH1100 works. A rim cylinder mounts through the door and drives a rim exit device or rim lock with a tailpiece instead, and the two are not interchangeable. If your hardware is an Adams Rite style storefront lock or a mortise lock body, the mortise cylinder is what you want; if it is a rim panic device, order a rim cylinder in the same Schlage C keyway so the whole building still keys together.
9) Is a zinc mortise cylinder good enough for a commercial entry door?
The TH1100 is built as a commercial cylinder in zinc. Zinc gives you a solid, corrosion-resistant body at a lower cost than solid brass, which is why it shows up on storefront and secondary commercial openings. For a very high-traffic main entrance on a security-graded schedule, a buyer standardizing a facility would normally spec a brass-body cylinder instead.
10) How many pins does the TH1100 cylinder have, and can it be rekeyed later?
Five pins in a Schlage C keyway. Five pin C is standard commercial pinning, so any locksmith can rekey it on the bench with ordinary Schlage pin kits and cut new keys from stock blanks. That matters if you turn over tenants or lose a key set: you rekey the cylinder rather than replacing the hardware.
