*Classifications from FM 4435 are based on design resistance loads. FM already has included a safety factor in its classifications and as a result, use of these classifications without adding an additional safety factor is appropriate for design purposes.

NRCA made arrangements with FM Approvals to allow NRCA contractor members to be sublisted under NRCA's listing. Sublisting will allow contractors to fabricate and install listed edge metal flashings in compliance with NRCA's approval listing. The sublisting arrangement is necessary because NRCA does not intend to fabricate edge metal flashings. NRCA has conducted research and testing necessary to obtain a listing and is offering sublisting opportunities to contractor firm members.

For information about sublisting under NRCA's approval listing, contact Carol Maggio, NRCA's manager of technical services, at (847) 299-9070, ext. 7574, or e-mail cmaggio@nrca.net.
