Itβs often the little things that cause the biggest problems in your commercial kitchen, and avoiding those big problems can be as easy as stocking up on a few little parts. While your glass filler may be the least of your worries, something as small as a broken gasket or a cracked filler arm can render this convenient tool useless. Pick up the necessary glass filler parts you might need down the road, and brush up on a little do-it-yourself repair knowledge, to save yourself money and time when the need arises to make a few repairs.
