Snap Lock Hunting Blinds utilize a unique system of interlocking panels that assemble securely in minutes without the need for hardware or tools. The Freedom Blind comes with multiple windows on all sides with clear, acrylic inserts and elastic draw strings to open and close silently. The rugged door utilizes a standard window system and has a durable latch that keeps the door securely closed. Also, the door is hinged on the inside to open or close with complete stealth. The new olive green color and 3D camo molded panels help decrease visibility of the Freedom Blind. Proudly made in the USA. This expansion pack is to be added to an existing 4’ x 4’ blind to increase it by 4’.
