Speak to a specialistBoth use the same P200 fabric and identical dimensions. The difference is attachment: Snap-On clips to a Falcon swivel arm via a galvanized karabina harness for fast installation and replacement. Lace-On is secured by cable ties or lacing cord through stainless steel grommets on fixed hoops, cages or frame mounts.
Lace-On is typically specified where mounts are non-standard, where tamper resistance matters, or where existing fixed cages are already installed.
The 7 ft Premium Lace-On is the size to specify for most US airports and airfields, and it is what we recommend unless your requisition calls for a larger indicator.
Specify the 12 ft Premium Lace-On where a large-format indicator is called for, and the 4 ft where a smaller indicator suits the position, such as helipads, industrial sites and OSHA-regulated installations.
If your requisition names a size or a specification, send it to us and we will confirm the match before you order. Non-standard sizes are built to order in the workshop.
Eight stainless steel grommets around the mouth hoop, evenly spaced. The grommet pattern fits most UK and EU manufactured cage mounts up to 1 m diameter.
If you're replacing a non-Falcon lace-on windsock and want us to verify compatibility, send us a photograph of the mounting and we'll confirm before you order.
