Alvin Professional Acrylic
Triangles |
|
 |
These acrylic triangles will not warp or
discolor because of age or handling. The machined finish and
hand-polished edges of the C series (clear) and F series (Fluorescent) meet
or exceed government specifications. The F series is extremely popular
because the refracted light has an illuminating effect on the drawing by
accentuating the triangle's edge All models feature a double-taper
cutout center for quick, easy lifting from any angle. |
