Plyco’s Series 20 walk doors are designed to be energy efficient, easy to install, and dependable enough to withstand the test of time. Unlike other metal walk doors, the Series 20 makes installation easier, and includes a universal swing feature that allows for up to 8 different configuration options. Contractors can customize their walk doors for a right or left hand in-swing/outswing, choose the key side placement, set the swing-radius, and more!
