DEFENDoor - Retractable Trellis doors

Retractable security gates, also known as expandable or concertina style security gates are probably the most popular security gate on the market today. This is due to its ability to retract out of the way when you don`t need it. Retractable security gates comprise a bottom track and top rail along which the gate run. Retractable security gates also contain nylon bushes to prevent direct steel on steel contact. Vertical steel uprights connected by scissor lattice flights make up the rest of the retractable steel gates. The steel uprights and lattice flights are designed in such a way so as to concertina together, making the security gate retractable; thus the security gate can be pulled to the side and thereby creating an unobstructed door opening or it can be easily expanded and locked to secure this doorway opening. .
