U-SHAPE is 2,5 times stronger

Edge types tested

Double hem is almost 2 times stronger

14

Edge types tested

â?ź

Reinforcing the edge with a bar increases 50% the resistance

15

Nail position comparative

â?ź

An inclined nail does not increase the resistance

Bendind the back of the nail (when possible) provides 3 times more resistance in the pulling test

Recomended fixings

Try allways to nail the edge in U-SHAPE position

Whenever possible use a stripe of wood over the fabric when nailing it

If there is no strips of wood available, the BIGHEAD NAIL is a good and balanced option If only SIMPLE NAILS are available use a metallic (no plastic) bottle cap as washer 17
