LA GARD 1947 4-Wheel Group 1 Upgrade Course
LA GARD 1947 4-Wheel Group 1 Upgrade Course
From the LA GARD 3390 Series Group 2M Mechanical Lock
Course Description
This focused upgrade course equips locksmiths with the precise technical knowledge required to specify, install, set, and support the LA GARD 1947 4-wheel Group 1 mechanical combination lock as a higher-security alternative or direct upgrade to the 3390 Series Group 2M. Emphasis is placed on the measurable security gains, the two critical installation differences that cause the majority of field errors, and the revised dialing sequences that end-users must be taught.
Learning Objectives
- Accurately compare the security ratings, combination capacity, and construction differences between the 3390 and 1947.
- Calculate and cut the correct spindle length for a 4-wheel lock and select the correct change key.
- Perform a complete combination change on the 1947 using the 4-number procedure and P/N 1315 change key.
- Explain the operational differences to end-users and document the new combination securely.
- Recognise when an upgrade to Group 1 / EN 1300 C / VdS Class 3 is warranted.
Module Overview
| Module | Focus | Key Take-away |
|---|---|---|
| 1 – Technical Differences | Ratings, combinations, construction | 100 million combinations + Group 1 rating = genuine security step-up |
| 2 – Installation Differences | Spindle length, change key, shared geometry | Add 1.000" (not 0.875") and use only P/N 1315 |
| 3 – Operating & Changing | Dialing sequences & combination change | 5 / 4 / 3 / 2 turn counts; always test door open |
