The following are examples of module frames that are compatible. Notice that the WEEB teeth are positioned completely under the edge of the module frame. The WEEB-UMC is only compatible with module frames that have a reinforcing box structure, as illustrated below. The following is an example of a module frame that is incompatible with the WEEB.
