Good Morning, I am looking to purchase combination locks, for gyms and schools. My question: Is it possible to have a small U joint placed on the body of the lock, positioned away from moving mechanisms, at the time of manufacture? The purpose is to attach identifying charms to the lock. I will be looking for different shapes and colors for the gym lockers only at this stage. Patent is pending. The purchase will be in bulk without packaging, as I will be packaging in my own company's name. Thank You 联系方式Co:lucky locks Add:6750 highview, cda, idaho Tel:1-702-5805650 Fax:1-208-7697045 Email:kamerade@live.com联系人:Ms. debbie dobritch国家:USA产品类别机械五金kamerade@live.com
