WinLok metal wall and ceiling panels provide a monolithic, accessible and concealed attachment system. WinLok allows easy panel removal by using the custom access tool – providing security/restrictive access unless the custom tool is used. The suspension is heavy-duty aluminum. WinLok panels can be installed flat, sloped, or segmented to simulate vault conditions. WinLok is used primarily in exterior applications that are subject to high wind loads; WinLok attachment clips provide a holding force of 100 lbs per clip, when using .050″ aluminum.
