Four-leaf Bi-Fold Counterweight Balanced Door

The ARCO A4000 is a custom-made counterweight balanced door designed for applications where security, superior appearance and minimal internal projection are required. It is particularly suited to very high openings, with only around one-eighth of the opening height needed for internal projection. The A4000 combines high performance with versatility in cladding and glazing options, while delivering quiet and smooth operation through its soft start/close motor system. With ARCO’s custom mechanism, the A4000 achieves over 100,000 cycles per year with low maintenance.
