Sizing tables
Quick reference
WindBands and Lasso Loops
| Tower diameter | WindBand | Lasso Loop |
|---|---|---|
| 18 to 50 in | WB50 · 110757 | LL50 · 110801 |
| Over 50 to 70 in | WB70 · 110758 | LL70 · 110809 |
| Over 70 to 100 in | WB100 · 110847 | LL100 · 110873 |
Per shroud: 2 under 8 ft, 3 for 8 to 12 ft, 4 for over 12 to 16 ft. One Lasso Loop per site, one Toolkit (110759) per crew.
SwingArm Trucks and Adapter Plates
| Truck | Thread | Tower diameter | Adapter Plate |
|---|---|---|---|
| Standard · 110344 | UNC | 24 to 42 in | 110445 |
| Medium · 110399 | UNC | 39 to 58 in | 110590 |
| Long · 110419 | UNC | 54 to 73 in | 110590 |
| Standard · 110050 | NPT | 24 to 42 in | Not stocked, call us |
Add 1 in to the diameter when WindBands are on the tower. Where sizes overlap, pick the smaller truck. Under 24 or over 73 in is custom.
Flags
| Tower height | Flag size |
|---|---|
| Under 100 ft | 10 x 15 or 12 x 18 ft |
| 100 to 150 ft | 12 x 18 or 15 x 25 ft |
| Over 150 to 200 ft | 15 x 25 or 20 x 30 ft |
| Over 200 ft | 20 x 30 ft |
Halyard length
Tower height x 2 + flag height + 20 ft
Round up to the next 10 ft. Example: a 120 ft tower flying a 12 x 18 flag needs 120 x 2 + 12 + 20 = 272 ft, so order 280 ft. Every halyard is cut to length.
Data sheets and documents
Specs for submittals and closeout
WindBands
How long does a WindBand take to install?
Under 5 minutes each the first time, and about 1 minute to remove and reinstall after a service visit.
Do I have to circle the tower to install a WindBand?
No. The Lasso Loop lets you set each band from one spot, so the bucket doesn't have to travel around the tower.
How many WindBands go on each shroud?
2 per shroud under 8 ft, 3 for 8 to 12 ft, 4 for over 12 to 16 ft.
Do WindBands get replaced after each service visit?
No. They come off and go back on, with no re-taping and nothing to throw away.
SwingArm Trucks
Which SwingArm Truck fits my tower?
UNC spindles: Standard 24 to 42 in, Medium 39 to 58 in, Long 54 to 73 in. NPT spindles use the Standard truck only. Add 1 in to the diameter if the tower has WindBands, and where sizes overlap, pick the smaller one.
How do I tell UNC from NPT?
Check the existing truck or the site drawings. Most towers are UNC. If you can't confirm it, choose "Not sure" in the Site Kit Builder and we confirm with you before invoicing or shipping.
Which Adapter Plate do I need?
110445 fits the Standard UNC truck (110344). 110590 fits the Medium (110399) and Long (110419) trucks. NPT towers are uncommon, so we no longer stock a plate for them. Call us for options.
Do I have to remove the existing boss?
No. The Adapter Plate installs over the existing boss.
Flags and halyards
How much halyard do I need?
Tower height x 2 + flag height + 20 ft, rounded up to the next 10 ft. We cut every halyard to length.
What's in the Flag Hardware Kit and Cleat Kit?
Everything to rig the flag on the halyard and secure the halyard at the tower base, tooling included.
