Cisco Aironet 1850 Series Deployment Manual page 8

AP 1850 has similar physical dimensions as other Cisco APs but with a few differences in physical appearance, most of which are
cosmetic changes to distinguish the different models. The mounting options and bracket configurations are identical and interchangeable
between Cisco 1140, 1600, 1700, 1850, 2600, 2700, and 3700 series APs.
