Don't know if it will help, but here's what was given to me when I bought a used Gabriels Signature Pro table. Unfortunately, there were no photos.
------------------------------------
INSTALLATION INSTRUCTIONS FOR GABRIELS “SIGNATURE PRO” POOL TABLE
1. Place (2) pedestals upside down, with the slots facing each other. Turn the table levelers clockwise until bottomed out, and then turn out three complete turns.
2. Place stretcher in slots, insert (2) bolts and washers on each side, through stretcher into pedestals and tighten.
3. With two people, carefully lift at the same time and turn over the assembly.
4. Place round feet under adjusters.
5. Place metal frame on top of pedestal assembly, insert (8) bolts, (16) washers (one on each side of frame) and nuts through pedestals and frame. Head of the bolts facing floor and tighten. Level frame assembly.
6. Place slates on top of frame assembly, insert (16) countersunk bolts through countersunk holes in slates, fit washers and nuts, level slates and tighten. (If necessary use slate leveling bolts through frame to level slates). We also suggest gluing slates together using slate stabilizer or equivalent. It is only necessary to level table as follows: level short rail end, then long rail, then other short rail.
7. Install cloth.
8. Cover tables with a blanket or other protection. Place long rails across table upside down. At end of table place short rail upside down. Insert large bushing into hole in rail (set screw side up) and insert long pin and tighten setscrew. Insert large bushing into corner piece and fit corner to short rail and tighten setscrew. Repeat this on the other side of short rail. When both corner pieces are attached to short rail, insert large bushing into other side of corner piece and insert large pin and tighten setscrew. Insert large bushings in holes in long rails on both ends. Fit the long pins coming out of the corner pieces into bushings at the end of the long rails and tighten. Repeat this on the other end.
9. Fit pocket liners in all the pockets; insert plastic buttons into pocket liners and holes in the rails. Be sure to make sure that the buttons fit into the liners so that the four protrusions on the button fit into the liners flush. Then with sheet metal screw and small washer insert into button from bottom, tighten until you feel a slight resistance, repeat to the remaining buttons.
10. Fit (12) angle brackets into the slots on bottom of rails with (12) bolts and star washers and leave loose. Fit the long rail blinds (skirts) on long rails only with (16) bolts and star washers and leave loose.
11. At the end of the table place short rail blind upside down. Get blind corner pieces (there are two right and two left hand pieces) locate on short blind for proper location. Insert small bushing with screw slot into corner piece and screw small pin into bushing until tight and loosen pin 1-1/2 turns, repeat on the other hole. Repeat on other ends of both short blinds.
12. Insert small bushing with setscrew into short rail blind and fit the corner piece to the short blind and tighten (if the corner piece is to tight or loose, adjust the pin either in or out) then tighten setscrew. Repeat on other ends of short blinds.
13. Fit short rail blinds with corner pieces attached to long rail blinds tighten setscrews (if loose or tight see step 12 for adjustment) repeat on other end of long blinds.
14. Insert the remaining bolts (8) and star washers into the blind brackets. Align the blinds to the long and short rails and tighten.
15. With two people carefully lift rail assemble at the same time to a blanket on the floor, then fit the assembly onto the table.
16. Insert the (18) rail bolts and washers into rails, carefully align the top rail assembly on table until pockets fit the same at all pockets. Tighten rail bolts.
17. Fit pocket nets with (2) bolts and washers then tighten. When installing side pockets compress the ring into a slight oval running with the long rail.
