Gardenode

A modular slat fence: aluminum posts with grooves, slats that slide in from the top, and rails, profiles and caps that finish each bay. Slats come in aluminum and composite, in solid, louver and openwork styles, plus laser-cut aluminum panels.

Yes. Both are 70-7/8" long and 13/16" thick and slide into the same posts, so you can combine them in one bay or change from bay to bay.

72-7/8" on center. Every slat is 70-7/8" long and spans exactly one bay.

Gardenode's guide is a hole about 15-3/4" square and 19-5/8" deep, filled with concrete that is not too wet. Your soil and local frost depth decide the final depth.

Yes, on steel base plates: 5-1/8" x 5-1/8" for the 3-1/8" post, 4-3/4" x 3-7/8" or a plate with cover for the 2-3/4" x 2" post. Keep a fence on base plates to 63" tall for wind load.

Yes: a galvanized steel brace in every third solid composite slat and in every composite louver and openwork slat. Aluminum slats need none.

The 3-1/8" x 3-1/8" post comes with one cap and one clip. The 2-3/4" x 2" post comes with one clip; order its cap separately.

Assume not. The grooves, clips and profiles are made for the Gardenode system, so order posts, slats and accessories from the same range.
