This toilet tissue holder has a single spindle design to hold one roll up to 4” wide with a minimum 1-1/2" core. The durable steel construction is chrome plated for corrosion and rust resistance, easy cleaning, and an attractive appearance. The spindle design conceals tension springs that prevent the roll from rolling freely, and when a roll is installed, the spindle locks in place, deterring theft and tampering and protecting your inventory. When the roll is depleted, you simply squeeze the cardboard core or remove it and squeeze the locking mechanism to release the spindle, and replace the roll. The theft-resistant single-roll toilet tissue holder measures 6-3/8" x 4-3/8" x 2-3/4".
