Congratulations on buying a new
Thermoglaze from Belshaw Bros., Inc. Please
inspect the unit carefully for damage or
missing pieces immediately after receiving
your system. Belshaw cannot pay for shipping
damage, because the freight company has
accepted the machine from Belshaw in good
condition, and is responsible for its safe delivery.
For your protection, each crate should be
inspected before signing the Bill of Lading to
report any visible damage caused by the
trucker in transit, and account for the number
of crates.
