Frequently asked questions

Common questions about COMPX CHICAGO from 3G Electric.

What are the key specifications of CompX Chicago file cabinet locks?

CompX Chicago file cabinet locks are available in round and rectangular body styles. Round models, such as the C5001LP series, have a body width of 1/2 inch, body thickness of 1-3/4 inches, and body height of 51/64 inch. Rectangular models, like the C5002LP series, have a body width of 1/2 inch, body thickness of 2 inches, and body height of 51/64 inch. They are offered in keyed-different and keyed-alike configurations, with specific key codes for consistent keying. These locks are commonly used on office filing cabinets, lockers, and storage furniture.

What is the capacity and chain length of CompX Chicago locking key holders?

CompX Chicago locking key holders have a 50-key capacity and are available with chain lengths of 4 inches, 6 inches, or 9 inches. They feature a black vinyl-coated finish for durability. These units are designed for secure key storage in industrial facilities, maintenance shops, control rooms, and plant operations. The locking mechanism prevents unauthorized key removal, and the chain allows flexible placement. Models include C4201-4-KA-6201, C4201-6-KA-6201, C4201-9-KA-6201, and C4201-4-KD, among others.

Are CompX Chicago key blanks compatible with all padlocks?

CompX Chicago key blanks, such as MPN D137-CLC, are specifically designed for duplication or replacement of keys for CompX Chicago padlocks. They are steel with a nickel-plated finish and feature 7 pins. Compatibility is limited to locks that accept this keyway and pin configuration. They are not universal and should be matched to the specific lock model. These blanks are commonly used in office furniture and cabinet lock systems requiring CompX Chicago keys.

What does keyed-alike and keyed-different mean for CompX Chicago locks?

Keyed-alike means multiple locks share the same key code, allowing one key to open all locks in a set. For example, CompX Chicago file cabinet lock C5001LP-1X03 is keyed alike with key code 1X03. Keyed-different means each lock has a unique key, so each lock requires its own key. Model C5001LP-KD is keyed different. The choice depends on whether you need centralized access or individual security. Keyed-alike is often used for multiple cabinets in one area, while keyed-different suits applications where separate control is required.

What materials and finishes are used in CompX Chicago locking key holders?

CompX Chicago locking key holders feature a black vinyl-coated finish over a metal base. The vinyl coating provides durability and resistance to wear in industrial environments. The chain is also vinyl-coated in black. This finish helps protect the key holder and keys from minor impacts and corrosion. The units are designed for wall mounting or placement in maintenance shops, control rooms, and plant operations. The 50-key capacity accommodates large key sets, and the locking mechanism secures keys when not in use.
