This is an Electrician's License Type 2 Skill Test Kit purchased on Amazon in May 2025. It's the Denko Sekka series, which was the cheapest. Please note the following points before purchasing, as it has been used: - No set screws for the non-threaded conduit box connectors - Rubber bushings have been cut - Metal fatigue on the tabs of the flush-mount multiple-gang frame - Washers on the terminal block have lifted due to overtightening of the screws - Joint box has been pre-drilled - Only the remaining ring sleeves are included
