in a roof valley and channeled to the inside corner of a covered gutter it is understood that the mesh 335 that is running adjacent to the front strip connector 325 can be formed into a variety of different shapes it is further understood that the mesh 335 includes corrugations not shown that extend at least partially through the trough 375 fig3 b is a cross sectional close up illustration of an exemplary trough 375 with v shape formed from three bends 381 383 and 385 and is illustrative of how rainwater typically travels along the mesh 335 into the trough 375 rainwater generally will travel under the mesh 335 and when encountering the barrier forming side surface h of the v shaped trough 375 travels down and eventually drops off from the end e of bend 383 which forms the low point of trough 375 in some instances rainwater will flow on the top of mesh 335 and flowing over bend 385 encounter side surface g which diverts the water into the bottom of trough 375 the entering water will drain through the apertures in surfaces h and g into the gutter not shown understanding that additional and or varied shaped troughs can also be formed fig4 is an illustration 400 of mesh 435 with trough 445 formed with a plurality of upward protruding barriers 475 and 485 in some embodiments combinations of the troughs shown in fig2 and 3a may be utilized as well.
