Offering more protection than standard drawer liners, the RG41 and LG41 series Protective Foam inserts can be used to further protect a drawer and the items stored in it without taking up as much of the drawer’s available depth as a dedicated tool storage foam insert. Good oil and chemical resistance for durability. Made from ¼” thick blue polyethylene foam, pre-cut to the drawer’s internal dimensions. Size your insert by getting your drawer nominal dimensions – typically by measuring the cabinet housing.
