yes, go for the brand Vitally.
google it.
cheaper ones in the rm3-400 range have unreliable suspended door hanging mechanisms.
these will probably lasts a couple of years before doors get jammed/stuck.
am using the Vitally Bifold King series.
the hanging mechanisms are mounted on rollers n doors are very smooth to operate even after many years service.
once n for all, try install this model.
u may contact Len @ 012 339 3662 (SS20/Damansara Utama).
can view samples there n price more competitive than thru Vitally themselves.
good luck.
