Home Hardware, Electrical and Heating

Three jobs share this aisle: secure, wire, heat

Most departments here do one of three jobs. Security and fittings cover locks, hinges, cabinet knobs, mailboxes and signs. Electrical covers conduit, switches, outlet boxes and cover plates. Heating covers space heaters and fireplace inserts. Ladders, flooring and doors round out the aisle. Begin with door lock sets and deadbolts if you are rekeying or replacing an entry lock, and measure the door before you compare anything.

Work out what you are replacing before opening any department. A like-for-like swap needs the old part's size, rating or part number: bore and hole spacing for knobs, hinges and pulls, trade size for conduit, volts and watts for heaters and elements. A new build needs a plan first, including where the power comes from, which circuit it joins and which finish runs through the room. Photograph labels, wiring and fasteners before you take anything apart.

Read the ratings before anything electrical or heated

Anything wired or heated is defined by its ratings. Switches and outlets must suit the circuit voltage and the current they carry, boxes must be big enough for the wires inside, and conduit and fittings must match in trade size and material. Heaters list watts, and a large heater should have a household circuit largely to itself instead of sharing it with other big loads. When a title shows a part number but no rating, treat it as unverified until you find one. See the switches and dimmers department for how load types are listed.

Questions about Home Hardware, Electrical and Heating

What should I measure before replacing any hardware?

For hardware, measure hole spacing, thickness and screw length. For electrical parts, read the voltage, amp rating and size on the label, and for heaters the watts. Photograph the old part and any label, since part numbers and finish names are the quickest route to an exact match.

Do I need a licensed electrician for these parts?

Like-for-like swaps of a switch, cover plate or light fixture, with the breaker off and the circuit tested, are common DIY jobs where local rules allow. New circuits, panel work and conduit runs usually need a licensed electrician and may need a permit. If you are unsure, ask before starting.

How do I match finishes when mixing hardware?

Keep visible items in one finish per room: door levers, hinges, cabinet pulls and switch plates. Finish names such as satin chrome, polished brass or matte black vary by maker, so take items from one line when you can, or compare samples side by side in daylight.
