Bolt the equipment to the floor
Precor recommends that the strength equipment be bolted down at all anchoring points. Bolting is made possible by removing the
end caps at the frame base and exposing the mounting holes that accommodate the bolts (see the accompanying figure). Replace
end caps when bolting is complete.
Important As floor materials vary, it is important that you consult a licensed contractor to advise you on proper bolting techniques and
appropriate fastener types.
Standards occasionally change or are updated. Precor recommends that you keep apprised of your local industry standards. Precor shall not
be held liable for failure to properly bolt the strength equipment to the floor.
