There are a lot of dangerous tools and products around the home that kids can get into, especially in your workshop and garage. This lockable cabinet gives you a safe place to store chemicals, paint, pest control products, sharp tools and other potentially dangerous objects. And because every bit of it is usable for storage, it holds a lot without requiring much wall space. Hooks and tension clips in the pegboard back and on both sides of the pegboard doors give you plenty of hanging room. The back of the cabinet and inner door frames can be fitted with adjustable shelves. It’s built as three easy-to-assemble boxes, and should take less than three hours to complete. The materials used are inexpensive: pegboard and 1x6-in. pine. The cabinet could be painted or stained and used in the house as an extra pantry, cleaning supplies closet or hobby center.
