Connection method: Extension of Blind Joint Parts

[Method of adding additional work to the frame]

Example: When adding a 1000mm aluminum frame to a 4000mm aluminum frame with a cross section of 30x60

1. Drill S holes horizontally on the right side of the 4000mm aluminum frame.2
. Drill D holes horizontally on the left side of the 1000mm aluminum frame.3
. Prepare pre-fit double Blind Joint Parts for the number of S holes.4
. Prepare pre-fit double joint nuts for the number of D holes.5
. Prepare 2 hexagon socket bolts for the pre-fit double Blind Joint Parts.6
. Pass the bolt (5) through the pre-fit double joint (3).7.
Insert the head of the bolt (5) into the S hole, then insert (3) into the S hole.8.
Insert (4) into the D hole of the frame (2) so that the tap is level with the groove.9.
Fasten to (4) with the bolt installed in (7). Do this for the number of grooves on both sides.
