Our Product Advantages
Over 30 years of dedicated R&D and manufacturing, creating more reliable KJ4-AP locks
Reduce Lock Failure Risk
Poor-quality materials may lead to hook breakage, unstable locking, and short service life. KJ4-AP is designed with selected materials for repeated exhibition use.
More Stable Locking
The improved inner-support structure helps the hooks engage more stably, reducing deformation and locking failure during repeated installation.
Protect Aluminum Profiles
Precision processing helps improve locking contact and reduce damage to aluminum profiles, supporting smoother assembly and longer system life.
Lower Long-Term Cost
A more durable connector lock helps reduce replacement frequency, installation delays, and long-term operating costs for booth contractors.
