Berta 100-Pack 90 Degree Cabinet Triangle Bracket - Durable Corner

In this review of the Berta 100-Pack 90 Degree Cabinet Triangle Bracket, the bottom line is simple: this pack is for DIYers, cabinet makers, and remodelers who need a reliable, small corner support in quantity. The reviewer found the brackets deliver consistent, sturdy support for cabinet and closet corners and are especially useful when you need to keep assemblies square during glue-up or when attaching a cabinet back to a countertop. Installation is straightforward and the package count makes these ideal for projects that require many connectors.

Key Features

• Package content: One hundred pieces per pack provide enough connectors to cover multiple cabinets or a full-room project without repeated orders.
• Material: Made of high impact, specially compounded plastic material that resists cracking and holds screws securely in place for lasting support.
• Off-center screw holes: The off-center hole positions give easier screw gun access into the corner, reducing awkward angles and speeding installation.
• Size: At 2-1/2 x 2-1/2 x 3/4 in each bracket, the connectors fit common cabinet and furniture corner dimensions without adding bulk.
• Function: The triangular design supports the back of a cabinet to the countertop and helps keep frames square while fasteners are set.

Who It's For

The Berta corner connectors are best suited for contractors, cabinetmakers, and hobbyists who assemble multiple cabinets, closets, or furniture pieces and need a dependable quantity of matching parts. Their simple, repeatable installation makes them practical for production or batch work where consistency matters.

Those looking for metal brackets with very high load ratings or decorative exposed hardware for fine furniture should look elsewhere. This product is engineered as a practical, functional plastic support rather than a visible decorative element or heavy structural anchor.
