What does a gate anti-sag cable kit do?

It provides adjustable diagonal support that helps keep a swing-gate frame square and reduces downward sag at the latch side.

Which gates can use this kit?

It is designed for framed aluminum single swing gates and double swing gate leaves, especially wide or long gates that benefit from diagonal support.

How many kits do I need for a double swing gate?

Use one kit for each gate leaf that requires support. A two-leaf gate may therefore require two kits.

Can the cable be shortened?

Yes. Cut the 20-foot cable to the required length and use the included aluminum sleeve to form and secure the finished loop.

Will it repair damaged hinges or a loose frame?

No. Damaged hinges, loose fasteners, weak posts, or frame damage must be corrected before the cable is tensioned.

One 20-foot stainless cable with connected turnbuckle, two 3/8″ × 4″ 304 stainless eye bolts with nuts and washers, and one 5/32″ aluminum double-barrel crimp sleeve.

Are all parts stainless steel?

The cable, turnbuckle, eye bolts, nuts, and washers are stainless steel. The cable crimp sleeve is aluminum.

Where should the cable be installed?

Run it diagonally from the lower hinge-side corner to the upper latch-side corner so it supports the free end of the gate.

How is tension adjusted?

Square the gate first, then rotate the turnbuckle in small increments until the cable is firm. Do not overtighten.

What tools are needed?

Installation generally requires a drill and bits, wrenches, measuring tools, a wire-rope cable cutter, and a crimping or swaging tool suitable for the sleeve.

Can it be used outdoors?

Yes. The supplied cable and primary hardware are stainless steel, and the crimp sleeve is aluminum. Inspect the assembly periodically.

TECHNICAL SPECIFICATIONS & INSTALLATION

The 20-Foot Stainless Steel Gate Anti-Sag Cable Kit provides adjustable diagonal support for wide and long aluminum swing gates. Installed from the lower hinge-side corner to the upper latch-side corner, the tensioned cable helps keep the gate frame square and reduces sag at the free end.

The cable can be cut to the exact length required. The connected turnbuckle provides precise tension adjustment, while two 3/8″ × 4″ 304 marine-grade stainless steel eye bolts create secure mounting points. Every supplied component is stainless steel except the 5/32″ aluminum double-barrel crimp sleeve used to secure the field-cut cable loop.

Questions & Answers

Find clear answers about Wall Topper sizing, 6-foot spans, included components, base-plate installation, concealed fasteners, style differences, finishes, maintenance and field fitting.

Sizing & Planning

What span is the aluminum Wall Topper designed for?

Each Wall Topper section is designed around a nominal 6-foot span between posts. The supplied horizontal slats are 6 feet long. Verify the actual field measurement before cutting, and plan one post per span plus one terminal post at the end of the run.

Which Wall Topper heights are available?

All five Wall Topper styles are offered in seven nominal heights: 1 foot, 1 foot 6 inches, 2 feet, 2 feet 6 inches, 3 feet, 3 feet 6 inches, and 4 feet. Select the height that fits the project, then review the exact style-specific material schedule shown on the product page.

How do I plan a multi-span Wall Topper run?

Divide the finished run into nominal 6-foot sections. Use one post for each span and add one terminal post at the end of the run. Confirm corners, end conditions, wall steps, field cuts, post locations, and local requirements before ordering.

Kit Contents & Style Options

What is included with an Alumission Wall Topper kit?

The selected kit includes Aluminum Post 2 Channels, two channel covers and one cap per post, an 18-inch zinc-coated steel post base and matching aluminum base cover per post, 6-foot aluminum slats in the selected style and height, the required pattern spacers where applicable, and stainless steel self-drilling assembly screws. Wall anchors are not included because the correct fastener depends on the wall material and project conditions.

How do Dallas, Los Angeles, Miami, New York, and San Francisco styles differ?

Dallas combines wide 5.5-inch slats with a four-slat 1-inch accent band. Los Angeles uses evenly spaced 5.5-inch slats. Miami centers a four-slat 1-inch accent band between wide slats. New York is a tight-stacked full-privacy design with size-specific finishing slats. San Francisco uses closely spaced 1-inch slats for a linear look. See the exact material schedule and proportional drawings on each style page.

Installation & Mounting

How do the base plate and base cover work?

Each post uses a zinc-coated steel base with a 4-inch by 4-inch plate and an 18-inch stem. The plate is anchored to a structurally suitable wall, the aluminum base cover slides over the plate to conceal the mounting screws or anchors, and the aluminum post slides over the steel stem. Plumb and align every post before installing the slats.

Can the Wall Topper be installed on concrete, masonry, wood, or steel?

Installation may be possible on concrete, masonry, properly reinforced wood, steel, or another structurally suitable wall when the correct substrate-specific anchors are used. Anchors are not included. The installer is responsible for confirming wall condition, edge distances, waterproofing, fastener selection, wind exposure, loads, and code or permit requirements.

Care, Ordering & Support

Does the Wall Topper require welding?

No welding is required for the kit assembly. Installation is a mechanical field-fit process that requires accurate measuring, cutting, drilling, leveling, fastening, and anchoring. Channel covers snap into place after assembly to conceal the slat-fastening screws.

Which finishes are available, and how should the Wall Topper be maintained?

Current finish options may include Black, Bronze, White, Dark Grey, Light Gray, and Wood. Availability can change by configuration. Clean powder-coated aluminum with water, mild soap, and a soft cloth; avoid abrasive pads, harsh chemicals, and tools that can scratch the finish.

What should I verify before ordering?

Confirm the total run length, selected style and height, number of 6-foot spans, post and terminal locations, corners or steps, wall construction, anchor plan, finish, field-cut requirements, access, wind exposure, and local rules. Product drawings support selection and installation planning but are not stamped structural or permit drawings.
