Structural Support with a Minimal Footprint

The Cable Bullet line post is a sleek, surface-mount, structural pass-through post, designed to support both your cables and top rail, with the smallest visual footprint possible.

Intermediate line posts are made from solid T6061 tempered aluminum for maximum yield strength. Each post includes pre-drilled cable pass-through holes every 3 inches on center, optimally sized for use with 5/32" diameter cable (max.). The elongated, tapered hole design offers the necessary support on level runs, while still allowing the cable to pass through without kinking along sloped spans.

Combine these posts with Signature series tensioning posts, or add them as infill for custom wood railing. Use cable spacer bars to maximize the view from your deck, patio, or stairway.

Clean & Minimal Profile

The slim 3/8-inch profile offers nearly zero obstruction to your view. Top mount intermediates feature a clean, press-fit base design (no ugly welds!) and matching base cover plate to hide the leveling screws.
