摘要: A triangular frame assembly is disclosed for supporting a safety barrier of boards above the edge roof during construction. The employs pivotal connections between base and lower stanchion member, diagonal brace, brace an upper member telescopically connected to member. angle can be adjusted accommodate wide range pitches by varying telescopic engagement members. pitch angles which used increased making invertable, adapting both ends thereof alternatively engage providing off-center connection variation invention provides rigid secured below eave extending eave.
