Safety 1st (brand)

Safety 1st covers more of the childproofing range than any other single brand, including cabinet, drawer, appliance, door and knob locks, so one system and one set of habits work across the house.

Not for: Renters or anyone who cannot drill or leave adhesive residue, and older toddlers who have already learned to defeat a given latch style.

Safety 1st Magnetic Locking System (line)

Hidden locks help restrict cabinet and drawer access without exposed latches; a magnetic key releases them.

Not for: Incompatible cabinets or households likely to misplace the magnetic key.

Which one fits you

paired knobs or handles, no install

Safety 1st Cabinet Slide Lock (line)

It slides over two adjacent knobs or U-handles in seconds with no tools or adhesive, so it suits renters and temporary setups.

Not for: Single doors, drawers, or knobs spaced too far apart for the slide to bridge.

Check before you buy

Lock type vs fixture. Match the mechanism to the hardware: magnetic or spring latches for framed cabinets, straps for appliances and odd shapes, slide locks for paired knobs. Most failed childproofing comes from a lock forced onto hardware it was not designed for.
Adult operability. You should be able to open it one-handed quickly; anything adults find annoying gets left unlatched. A lock that is routinely bypassed protects nothing.
Mounting. Prefer screw-in for permanent high-risk spots such as cleaning products; adhesive only on clean, smooth, non-porous surfaces. Adhesive is the most common point of failure under repeated toddler pulling.
Gap when latched. The door or drawer should open only a small gap, too narrow for fingers to get through. Wide-gap latches let children reach contents or trap fingers.

Questions

Do I still need locks if I move chemicals up high?

Yes for anything left low, but height plus a lock is better than a lock alone, since children eventually learn to defeat most latches.
