3-Channel Post
Use the bracket inside the appropriate channel to secure the end of an aluminum slat to the post.
These compact stainless steel L-brackets create a secure 90° connection between Alumission aluminum slats and posts from inside the post channel. The concealed placement keeps the finished fence or gate clean while supporting the slat at the connection point.
They are primarily used with the Aluminum Post – 3 Channel and the Aluminum Side Post when the selected connection does not use a separate screw channel with a snap cover. Each bracket installs with two included stainless steel #8 self-drilling screws—the same screw type Alumission sells separately.
The small 90° bracket sits inside the post channel and connects the slat to the post without a large exterior bracket.
Use the bracket inside the appropriate channel to secure the end of an aluminum slat to the post.
Ideal for side-post connections where there is no separate screw channel and snap cover.
The compact bracket remains inside the channel so the primary connection is less visible after assembly.
Each bracket uses one included #8 screw into the post side and one into the slat side.
Both the brackets and supplied #8 self-drilling screws are stainless steel for compatible outdoor fence and gate projects.
The L-bracket is formed from 0.06″ thick stainless steel with two mounting holes.
The included stainless steel self-drilling screws are the same type sold separately by Alumission.
Choose 10 brackets with 20 screws or 50 brackets with 100 screws.
Drive the screws until the bracket is secure; do not overtighten or distort the bracket or aluminum profile.
Included: Your selected pack size: either 10 stainless steel L-brackets with 20 stainless steel #8 self-drilling screws, or 50 brackets with 100 screws.
Sold separately: Aluminum posts, slats, post covers, snap covers, drill/driver, bits, and any other project-specific hardware.
Review the bracket dimensions, stainless steel construction, included screw quantities, and compatible post-channel applications.
Confirm slat position and bracket clearance before fastening. Keep the bracket square to both profiles and avoid overtightening the self-drilling screws. Final connection requirements depend on project dimensions, wind exposure, slat orientation, post spacing, and local code.

They connect Alumission aluminum slats to aluminum posts at 90° from inside the post channel.
They are primarily used with the Alumission 3-channel post and side post, especially when the connection does not have a separate screw channel with a snap cover.
Yes, when the selected post channel and slat orientation provide proper access and support for the internal bracket.
They install inside the post channel, which keeps the connection discreet. Visibility depends on the final profile and cover configuration.
Yes. They can be used for compatible aluminum fence and gate assemblies that require an internal slat-to-post connection.
Choose 10 L-brackets with 20 screws or 50 L-brackets with 100 screws.
Two stainless steel #8 self-drilling screws are included for every bracket.
Yes. The included stainless steel #8 self-drilling screws are the same type offered separately by Alumission.
Each bracket has 0.50″ legs, a 0.75″ width, 0.06″ thickness, and two 0.19″ mounting holes.
Position it inside the post channel with one leg against the post and the other against the slat, confirm alignment, then secure both legs using the supplied #8 screws.
No. Tighten only until the bracket is secure. Excessive torque may distort the bracket, strip the aluminum, or damage the finish.
