Spring-Fast® Composite Grommet Edging covers sharp edges of panels that come in contact with witre and cables and mechanically lock on indefinitely with finger pressure in only seconds per foot. They provide a significant time reduction in assemblies. A long-term reliability solution that replaces nylon caterpillar plastic gromments and associated solvents, adhesives, and ancillary materials to protect critical equipment from failure due to wire chaffing.
Spring-Fast® Grommet Edging is approved by the FAA and U.S. Department of Defense per NASM 22529/a and NASM 22529/2 for all aircraft applications. Meets FAR 25.853 for flammability and MIL 1344 for shock and vibration. Spring-Fast® is available for 8 different sheet thickness ranges from 0.025 to 0.260 and can be purchased in either 10 piece packs of 12.75" long pieces, or 25 or 100-foot reels. Use Spring-Fast® BAP and SL series for flanged lightning hole and three-axis contours. The BAP Series Flexi-Grommet is perfect for roll formed edges and small lightening holes. Where wires are routed in the same plain as the sheet metal, the Spring-Fast® SL Series provides a trim characteristic for all edges with or without cabling nearby.
Spring-Fast® is used in a wide variety of aviation and aerospace applications:
• Lightening Holes
• Wing Sections
• Air Traffic Control
• Racks • Tail Sections
• Tactical Satellite Emulators
• Navigation Systems
• Electrical Power Centers
• Ground Control
• EAU (Electrical Avionic Units)
• PSU (Personal Safety Units)
• APU (Auxiliary Power Units)
• IFE (In-Flight Entertainment)
Ive used the M22529/2 for the better part of nine years - finally someone got it right replacing the older glued nylon MS21266. No more pli-o-bond, no more acetone or MEK, clean and simple to use. Ive static loaded it to 20G - very impressive and use a smear of RTV if the seam gap is greater then 1/32
Very high quality item with super fast shipping.
For what I wanted to use the flex for, it was a bit too high quality. It is a bit thicker than the white nylon flex that is more common and hence if the metal hole is not sufficiently large, then there is not sufficient space for all. It might be that ACS consider also stocking the lighter nylon flex.
I love it when a product works exactly as advertised. It is easy to cut into the lengths you need with a simple pair of side cutters. I used my grommet edging to line the lightening holes in my wings to prevent chafing of wiring harnesses. It installs very easily by just pushing it down onto the edge, and is secure enough that it will not move again, yet not so secure that you cant move or remove it if you have to. Its a bit pricey, but it does exactly what I wanted and is one of the few things about my project that was easy to install.
I used this to prevent chafing of wires in landing gear wells where wires run close to ribs and bulkheads. Works perfect and I put a little adhesive to make sure it stays put.
THe product was great. The customer service was even greater. John Cash is a great person to deal with at Aircraft Spruce. Thank you very much. Will definately do business with you again.
Needed to protect an aluminum fuel line passing through an oblong hole. This will work perfectly!
I used this around a lightning hole in the seat ribs where wires were close. It was very easy to install and appears to create a nice smooth edge that will not chaff wires.
