Product Overview

The Rigid Flex Banner Tensioning System by United Sign delivers a secure, taut frame for large banners. Each kit includes:

• 10″ or 4.5″ aluminum J‑Hook with nuts and washer

• Options for 8″ or 2.5″ lateral adjustment per side, with half the cost of other framing systems 

Compatible Banner Materials

• PVC vinyl (13–18 oz) – strong, vibrant, and durable

Calculating How Many Tensioning Brackets Are Needed

When planning your installation, it’s critical to determine the correct number of tensioning brackets to ensure the banner stays evenly tensioned and secure. The general rule of thumb with the Rigid Flex Banner Tensioning System is one bracket for every 4 feet of perimeter, plus additional brackets at each corner for extra support.

For example, if your banner is 12 feet wide and 24 feet tall, you would calculate the perimeter as follows:
12' + 24' + 12' + 24' = 72 feet total perimeter.

Divide this by 4 to get the number of intermediate brackets:
72 ÷ 4 = 18 brackets.

Then, add 4 extra brackets for the corners:
18 + 4 = 22 total brackets needed.

Spacing should be evenly distributed along each side, so tension is consistent across the entire frame. Proper spacing prevents sagging, minimizes stress points, and ensures a clean, drum-tight finish.

Installation Diagram

• Each side: level the rails, install J‑hooks and mount anchors → clip in banner edges → tension → check corners

• Corner alignment is crucial for clean edges

---

Tools & Equipment Needed

• Cordless drill with masonry & metal bits (Rotary hammer drill)

• Cement anchors or self-tapping screws

• Level, tape measure, chalk line, screwdriver set

• 1″ conduit or pipe (for banner pockets)

• Soft mallet

• Ladders, scissor/boom lifts, and full fall‑protection systems (OSHA‑compliant)

---

Step-by-Step Installation

1. Site Prep & Assessment

• Verify building surface strength (brick, concrete, structural metal)

• Avoid light siding; fix degraded walls first

• Mark corners and level chalk lines for the frame

2. Frame Setup

• Pre-drill holes using correct bit

• Secure horizontal rails, then vertical rails

• Use level and square attachments before tightening

3. Banner Attachment & Tensioning

• Slide 1″ conduit through banner hems

• Attach to J-hooks: begin at one corner, work around perimeter

• Use mallet to seat tension clips

4. Final Inspection

• Smooth out wrinkles

• Tighten any loose clips/anchors

• Ensure no protruding hardware remains

---

Building Challenges & Pitfalls

• Light, hollow siding may deform under load → avoid or reinforce

• Cracked/bricked surfaces risk anchor failure → repair mortar first

• High-wind areas → use mesh banners

• Incorrect anchor spacing or misaligned frame = sagging/wrinkling 

---

Safety & Maintenance

• Use harnesses and secure lifts (OSHA-compliant)

• Perform post-install inspections (after storms and every 3–6 months)

• Clean banners gently and inspect clips for corrosion, replace if necessary

Examples & Photos and things to Watch For
