DO NOT PURCHASE THIS ITEM - It is impossible to see or feel the threading of the cable through the top support beam and on the pulleys. Then when the cable frays (and the items becomes an unusable piece of junk) Titan refuses to stand behind the product and replace the cable. They claim you "misused" the item even though it is absolutely not possible to see into the arm or otherwise feel the threading of the pulley system. Shame on you Titan. If you are looking at this unit - DO NOT BUY!!!! Save your money or look elsewhere. I seriously doubt Titan will allow this review to post so as to warn future customers. Save your money - If I could give a "zero" star I would - I feel like I just got robbed of my $600+ dollars.
