Tolerances: At our warehouse, we do "rough
cuts" only, with best tolerance of 1/8 inch .
If you want to cut our fiberglass yourself, here are a
few helpful notes: A fine-toothed hacksaw will do the
job on very small quantity jobs . Be certain to support the back
side of the tube / rod when cutting through to avoid splintering
of the fiberglass as the blade comes through the back . Rest
the fiberglass on a piece of scrap wood at the point of the cut
. Also, a wrap of masking tape at the cut point also helps .
Also support the piece of fiberglass level with the cut all
along its length . You do not want the ends to fall down as the
cut nears completion, splintering the last few strands of
fiberglass on the back side of the cut .
Do not breathe the fiberglass dust . It is a
good idea to cut outdoors . Use a good protective mask .
you have the equipment, a far better cutting method is by use of
a power miter saw or "chop saw" with an abrasive blade . These
tools will give you a perfect, square, smooth cut every time .
NEVER use a toothed blade .
The finer the abrasive on the abrasive cutting blade, the nicer
the resulting cut, but the cut will also take longer than with
coarser blades . Even the very common (and cheap) "metal
cutting" or ceramic / concrete cutting abrasive blades that fit
these tools will work fine, and they are commonly available at
Home Depot and other home improvement and hardware stores .
all cases, use care when cutting, use breathing protection, and
cut outdoors where possible . If you are not knowledgeable in
the use of these types of tools, seek professional help.
