The VT4889-AF array suspension frame
is crafted of 6061 Grade heat-treated
aluminum. It includes 11 (eleven)
attachment holes for fitting 6.5-ton
shackles.Each of these holes is fitted

These holes are set on approximately
102mm (4”) centers. Each hole has an
I.D. (Inner Diameter) of 25.4mm (1”).
The frame includes four receiver blocks,
designed to attach Hinge Bars from the
VT4889 enclosures.These blocks are
made of 7075 Grade aluminum.They
are coupled with Grade 8 bolts, and the
attached steel quick release pins are
secured with stainless steel restraining
lanyards.
The VT4889-AF weighs 45 kilograms
(100 lbs.) It measures approximately
