What is this post connector used for?

It creates a concealed 90° connection between Alumission aluminum posts. It can form a T-shaped joint or a corner in a fully framed assembly.

Does it fit every Alumission aluminum post?

It is designed to fit the compatible 1-1/4″ internal post cavity used across Alumission aluminum post profiles. Confirm the receiving cavity is clear before installation.

Can it be used for a sliding gate?

Yes. It can connect post profiles at 90° when building or extending a fully framed sliding-gate assembly.

Can it be used for swing gates and fences?

Yes. It can form concealed corners in fully framed swing gates and aluminum fence-frame assemblies.

Is this connector made from aluminum?

No. The connector body is steel and is powder coated black. It is designed to fit inside Alumission aluminum posts.

Will the connector show after installation?

The main connector and bolt are concealed inside the joined profiles, producing a cleaner finished frame.

What size is the connector?

The connector is 1.250″ square with a 6.130″ drawing length, 0.125″ wall thickness, and a 0.375″ internal steel block.

No. The connector is intended for a bolted internal connection, so welding the aluminum profiles is not required.

How is the connector installed?

Slide the connector into the receiving post cavity, align the intersecting aluminum post at 90°, install the included bolt through the prepared connection, square the assembly, and tighten it securely.

Can I use it to connect posts in a T shape?

Yes. A T-shaped connection between a vertical and horizontal Alumission post is one of its primary uses.

Are additional screws included?

The connector includes the stainless steel bolt and washer. Any project-specific retaining screws or other hardware must be ordered separately unless specifically shown as included.
