The case I have is a Vanguard 62" Guardforce 50 BMG travel case w/wheels.
Manufacturer number is GDS9290CW.
Portable Long Gun Safe GDS-9290CW Outside: 63 x 13 1/2 x 6 3/4
Inside: 62 1/8 x 12 5/8 x 6
Weight: 26.89 lbs
This case comes with four internal tie down straps to securely hold heavy rifles in the center of the case. THe straps may cause some wear on some barrel finishes so it is wise to put an old sock(CLEAN) between the rifles and the straps to pretect the finish on the steel and stocks with the heavy weight of the rifles.
These are not water proof but they are have two combination locks and are quite sturdy. For the money hard to beat.
