Can this sink be supported soley as a wall hung sink?

There is a Cheviot Products Inc webpage and telephone number. The company is located in British Columbia, Canada but has an 800 number. The website contains specification drawings for this model, but it can't be determined whether the wall mount is stable enough on it's own. An alternative is to affix a 2 x 4 to the wall studs under the sink basin once it has been mounted so that it will create a ledge for the sink to rest on for stability. Be sure to get the Accessibility Planning Guide for Bathrooms from your county building department for the exact measurement of the sink clearance from the floor to the bottom of the sink so that it will clear the wheelchair and be ADA compliant.
