Attaching dolly boards to subs
« on: February 07, 2008, 02:17:15 pm »

 We are in the process of building dolly boards for our jbl dual 18 subs, tired of the hand truck method. We have eight of them now and the dolly boards will make for faster load/unload times. I do not wish to mount casters directly to the backs of the cabinets because of packing space but rather use dolly boards on the ends as this is how they are transported now. My question is how do you attach your boards, T nuts in the cabinets with bolts, dzues style fasteners, straps or other means? Ideally I would like to be able to attach the boards to the ends of the sub quickly and more importantly securely. I like the idea of a dzeus type first with a strap arrangement lastly, less stuff to keep up with or misplace  All opinions pros and cons are appreciated and any links to find specialized fasteners.
Thanks
Bill

I rented some EAW subs that used magnets and steel inserts in the cabinets. Worked ok, however the assebler should have used some blue locktite.

Did they make it over door thresholds and dock plates and ramp transitions?

If in the U.S., 3/8"-16 Tee nuts inside the cabinets, and some form of grip knob on the bolt:

A search on the part number in the drawing will take you to the proper page in their online catalog.  There are metric versions for folks who require them.

Best regards,

I prefer the way RCF does this. Their subs have a machined steel boss that is routered and screwed into the cabinet with a backing plate, and threaded for the casterboard T-bolts. I'd worry that a T nut would get loose inside the cabinet since the casterboards would be frequently removed.

Epoxy it in, or use one of these:  

Mcmaster Carr part number: 90611A450

A weld nut with holes-just use screws to mount it.

I have four of the SRX728 dual 18" subs (presumably the same as yours) and built some home made dollies last summer. I used 3/4 ply and made the platform slightly larger than the width of the back (not bottom) of the cabinet (3/4" buffer on each side). I put a 2x4 bumper on the front end and carpet on the deck (carpet adhesive and some 1/2" staples well seated). I trimmed a couple pieces of E-track  into 2" strips (the monting rails for load straps in a truck) and bolted them to the bottom of the dolly. The sub rides face up with a cover on it and I put an SRX725 (dual 15 w/horn mid/high box) face down on top of the sub (also in a cover). The whole thing is strapped with a load ratchet strap that stays attached to the Etrack on the underside of the dolly. When I get to the gig, I loosen the strap and slip it off one end. Then we pull the mid/high box off. To upright the sub, I just grab a handle on the 2x4 end of the dolly and lift- easy peezy. We used 4" guitel locking casters. So far, the system works great. Good luck.

Straps seem to be the best option for us. We just built custom cards for our whole rig out of 3/4 pine plywood coated with some truck bed liner. Make sure to cut the cards a little bigger than the actual speaker to provide a protective bumper for the speaker. Adding some tuki covers has kept our speakers looking brand new for the past year and a half. When it comes time to stack the rig we can take the straps from the carts and use them on the FOH rig, Drum Fill, and Side Fills (all black straps of corse).

The Vertec dolly boards are quite good, if you have room to attach the latching post to your box. They are mechanically fastened, easily attached/removed and stackable when not in use.
