this mount work exactly as state and be infinitely adaptable up to a certain point - the adjustable `` leg '' extend out to increase the overall circumference ... sorry I do not measure the maximal span BUT in my case , it be about a inch short of be wide enough to span the mount hole on the Epson Powerlite 8350 that I buy it for . however , the company doe sell longer `` leg '' for a couple of dollar each , or there be a alternative model # that come with longer extension leg ... but some swift search on Amazon show you that these option be not available via Amazon `` Prime '' vendor , and I do not have time to mess about send stuff back , so ... however -lrb- 2 -rrb- if you have four short nut & bolt to spare -lrb- trip to Home Depot Hardware for such a pack - quarter inch circumference by 1 inch long + 4 washer -rrb- you can just join two of the `` long '' leg to two of the additional `` short leg '' that be pre-supplied in the kit and the result extra reach do span the gap perfectly well to accommodate say Epson 8350 projector . I will upload a photo -lrb- picture worth a thousand word -rrb- ` cos this be a quick & handy fix for load of other who write about this piece of kit not be suitable for the Epson 8350 when Amazon be unwittingly display it in the `` what other people buy when they purchase this item '' type of section when you buy a Epson 8350 . Hope this help - otherwise , it be sturdy enough and I should also add it be infinately adjustable for side-to-side leveling , front-to-back leveling , have a extender bar if you need to drop it down from a high ceiling and also have a pivot plate that attach to the ceiling to accomodate a angled vaulted ceiling like we have . go for it , but not if you have a Epson 8350 and you do not want to mess about with the afore-mentioned 4 extra nut & bolt like I use -lrb- hence the 4 star & not 5 -rrb- ... but in all honesty if you can put the thing together in the first place , you can just as easily add four extra bolt & save yourself $ 20 or so vs the other model with the `` long leg '' . ooh-err , missus .
