Good quality exact fit
Installed regularly on a 172N. Expensive and dont last long
Bought and used on a 2002 C172R. Lord makes these mounts with a space between two rubber donuts. The space allows the mount to have translation in all directions removing the stress from the supporting bracket. The bad news is they dont last long - and they are expensive. The spacing between the rubber halves is usually where the mounts begin to tear as the rubber dries out. In contrast, Cam-Lock and some other cowl mount makers use hard rubber, with no space. They do last longer - they are a lot cheaper, but these hard rubber mounts translate torsion stress into the aluminum mounts if not perfectly aligned to the attaching cowl. The mount will eventually break where they attach to the aircraft. Alignment is critical during the interface between the cowling and cowl fastener so any stress the cowl receives, is distributed equally across all of the mounts. This is easier said than done.
No. These are for use with 2600/2700 camlocs which are not included with the mount.
Per the supplier: J-7444-36 is about twice as stiff as J-7444-14.
Per the overview description the J-7444-24 is used with 2600/2700 series Camloc style studs, and the J-7444-42 is used with the larger diameter 4200 series studs.
