One other question: would 1/4" x 3" lag bolts be a good choice for mounting?

The 1/4" x 3" lags should work, as long as you have some wood underneath the roof (like rafters or a strategically placed piece of 2"x4").... and put some sealant under the feet so that water does not follow the lag and cause a leak. These things work pretty well for small antennas, VHF or TV.... would not want to put a large high frequency antenna on one, wind loading and vibration become a problem.

The 1/4x3 size lag bolt would definitely be strong enough with some caveats . . How solid is the material and the foundation into which they are being screwed? Hopefully you will be able to "hit" a rafter or other structural member supporting the outer roofing materials. Some composite shingle roofs are sheathed just using 1/2" plywood, so if that is all that the lag screw is going into not much is holding, and the length of 3" is just giving you a false sense of security. Second, the lag screw used should be "all thread" along its entire length. Some lag screw designs are "thread-less" for some distance along the shank next to the head. That design should definitely not be used in this application. Also, I would suggest using a flat washer (minimum 1" to 1-1/2" and known as a "fender" washer) between each lag screw head and the tripod leg mount hole. This will help to not deform the tripods' soft metal as the final tightening takes place and provide better distributed contact support. Use stainless steel washers for this to minimize future rust. . . One last thing . . After you figure out where each leg base will contact the roof for the support issue, squirt or put a dollop of roof-seal-compound under each between the mount and the roof, so that the lag being screwed in will actually carry sealant with it to insure a watertight seal. The excess that is compressed out in the process can be smeared around the immediate attachment point to complete a seal to your satisfaction. A throw-away 59 cent 1" plastic putty knife will be a valued investment! - I've been very satisfied with the mount used within the scope of its design. - - Hope this is in someway helpful . . Bob M.

if you are mounting to an asphalt roof, 5/16 x 2 inch would probably be a better choice. That is what was used to mount a Dish antenna for me.

Your weakest point will be the mounting screws.... Use 'Lag bolts' into solid wood...... "That oughta do it!"

will accomodate mounting holes that are spaced : 3" x 3" , 4" x 4" , 8"h x 4"v , and 8" x 8"

Any half moons will work, as long as the length is the correct size. Just look under 18 or 20 inch bolts.

You could use an adapter to take it up from quarter inch to 3/8 inch. I've driven lag bolts with it and it does fine.

You should be fine using longer bolts. I would recommend pre-drilling first just to protect the stud. It's going to take enough abuse. I wouldn't use anything smaller then a 3" just because you will have a weak point with the sheetrock being between the stud and the bracket. Unless you cut out the sheetrock just big enough for the bracket...?

Don't have a figure but, I can say that in low gear it will drive 3x3/4" lag bolt, lots of lags without pre-drilling.

I was able to line up 1 set of vertical mounting holes on a wall stud and used 4" lag bolts. It's also on the side of a closet, so the location might discourage prying efforts.

We attached these to the molding on either side of our 9 foot garage doors. The lag bolts are 106 1/2 apart. There is an overhang of 3/4 inch on the inside of the molding. I tried to attach a picture but didn't know how.

Yes Much better that way. Find stud locations and use lag bolts 1- 1/2 long

Go down to your local hardware store and tell them what you are trying to do - they will point you towards the right hardware. Briefly, you're going to want a HSS (high speed steel) or a titanium carbon-coated drill bit and the right screws. Make sure you're not exceeding weight specs (for the mount OR your wall)

get 4 lag bolts from the hardware store for less than a dollar, drill pilot holes into your bench and mount... pretty self evident.

Yes on mounts because of the swivel design and maybe on lag bolts:It depends on your total weight divided by two and if your doing full body weight or partial suspension vs dynamic gymnastic routines. If it was me i would install/mount a 2x4 between rafter joist and replace lag bolts with same diameter machine bolt,lock washers and nut. This is a simple modification and it will be SOLID! If you decide to go with lag bolts I would always inspect prior to use.I like your idea and I may try it myself, good luck!

They provide a couple sets of different size mounting screws, it should have what you need.

Yes, if you're going to put the lag bolts into a stud, you'll want to drilla pilot hole first. It will make it much easier to put the bolt in.

I would install lag bolts in the wooden stud at the center and just use toggle bolts at the ends. These TVs nowadays are not very heavy and the toggle bolts can easily hold 75 pounds apiece in drywall.

Yes. You will need a couple bolts to mount depending upon your application.
