Reverse action, single acting spring hinges are for automatic opening of door.
For maximum versatility use all spring hinges or a combination of spring hinges and ball bearing hinges. Do not use plain bearing hinges. Hager does not recommend using spring hinges on doors over 7'0".
Strong wind conditions, drafts, carpeting drag, twisted/misaligned frames, or weatherstripping on doors may require additional spring hinges. Full spring tension may not be required on all hinges.
