About This Device
Outdoor installs favor heavier cable - shielded, UV-jacketed, gel-filled Ethernet that runs 6 mm and up - and the W2255's I/O sealing accounts for it with this larger-bore gasket. The 170946-000 covers 5.5-6.5 mm jacket diameters, compressing around the heavier cable as the I/O cover closes. Forcing thick cable through the smaller 170945-000 gasket pinches the jacket and opens leak channels; the correct bore seals clean. Together the two sizes cover the cable choices a W2255 install realistically makes, which is why fleet site kits carry both and let the field measurement decide.
Upgrading a site to shielded outdoor Ethernet without upsizing the gasket trades one reliability problem for another - the bore has to follow the cable.
Measure the jacket, confirm 5.5-6.5 mm, seat the gasket in the I/O entry, and compress with the cover. If the site's cable measures under 5.5 mm, use the 170945-000 for a proper seal.
Cloud Care Networks stocks the Cradlepoint 170946-000 alongside the gateways and routers it supports, so IT and field-service teams can consolidate antennas, spares, and replacement hardware on a single order.
