Metal Bifold Door Lock - Child Safety Slide Lock for Double Doors

In this review of the Metal Bifold Door Lock, the bottom line is simple: parents and pet owners who need a no-drill, heavy-duty solution to keep toddlers, cats and dogs out of closets and pantries will appreciate this product. The reviewer found the four-pack of sliding aluminum locks effective on typical bi-fold doors and praised the ease of use and durability. If you want a quick, removable childproof option that prevents little fingers from being pinched and pets from raiding laundry or snack areas, this lock is worth considering.

Key Features

• Designed for bi-fold doors: The lock is built specifically for double bi-fold doors and keeps small children and pets from opening the door joint where fingers can be pinched or access gained.
• 7' extended slide rod: A double-sided extended handle spans the joint and provides firm locking action without relying on plastic parts that wear out quickly.
• Sturdy aluminum construction: Made from metal rather than plastic, the lock resists bending and shows better longevity in everyday use around busy pantries and closets.
• No-drill installation: The lock slips over the top bracket and slides closed to lock the doors without tools or permanent hardware, so it can be repositioned or removed easily.
• Fits common door thicknesses: The sliding bracket accommodates most bi-fold door thicknesses in the typical range, making it compatible with hallway closets and laundry cabinets.
• 4-piece pack: Four locks are included, allowing multiple doors to be secured in a single home or spare pieces for different rooms.

Who It's For

This lock is best for households with young children or curious pets that can open bi-fold doors to reach hazardous items or create messes. It is particularly useful on pantry, laundry room and hallway closet doors where a top sliding lock prevents the doors from unfolding at the center joint.

It is not intended for single swinging doors or complex locking needs where keyed or recessed hardware is required. If you need an integrated latch for non-bi-fold doors or a permanent, tamper-resistant installation, other specialty locks would be a better fit.
