How to Use of 90 degree Brackets
Features of 90 degree Brackets: This type has a protrusion that fits into the frame groove.
The protrusion acts as a rotation stopper during fastening work, making it easy to work with.
It can be mounted in either direction.

L-shaped connection
Cross Connection
90 degree Brackets for two-row grooves are also available.
Technical Information of 90 degree Brackets
■ For the squareness of the square 90 degree Brackets, please check the squareness tolerance table .
■ 90 degree Brackets allowable load concept
here indicates the load at which the 90 degree Brackets can maintain its position (without breaking or slipping) when all mounting holes on the bracket are fixed with bolts and a load is applied.
How to Install the Washer and Bolt Set (-SEC) of 90 degree Brackets
■ How to install HBLFSN6-SEC, which is a set of the spring washer bolt for the aluminum frame 90 degree Brackets HBLFSN6
This product requires more care when tightening than other series of spring washer bolt sets, as the bolt head interferes with the bolt.
We will introduce how to install it.
STEP 1 Installation sequence
STEP 2 Tightening the hexagonal bolts

Of the two holes, installation will be done through the hole mentioned above.
STEP 3 Adjust the position of the spring washer on the bolt
, the heads of the previously tightened bolts
will interfere and installation will be impossible.


Finally, tighten the hex bolt by twisting it.

If it is difficult to pre-tighten one side, we recommend using the following product.
Case 1 When changing the bolts without changing the 90 degree Brackets
HBLFSN6-SET (changing the applicable bolt and nut set for additional work)
Case 2 When changing the bracket without changing the bolt with spring washer
HBLFSH6-SEC (changing to a one-sided oblong hole bracket)
The hole on one side of the bracket is an oblong hole, so even if you use a hexagonal bolt with an integrated washer, the bolt head can be used for installation without interfering.
Product Comparison Information of 90 degree Brackets
There are two main methods for connecting aluminum frames:
| Bracket Connection | This is a connection method in which a nut is inserted into the groove of the aluminum frame and then fixed with a bolt. Since no additional work is required on the frame, it is inexpensive and can be installed in any position. | |
|---|---|---|
| Joint Connection Blinds | This method involves drilling additional holes into the side of the frame and connecting using a special joint. Since no brackets are used, the corners are neat and tidy, and it is recommended for those who want to avoid interference. |

This is the most conventional type. | This type has a rib (side) on only one side, making it easy to turn the hex wrench. | The long protrusion serves as the nut lock, eliminating the need for fine adjustment of the nut position. | The protrusion is on one side only and is useful when connecting frames/plates. | One side has an elongated hole. The bolt head does not interfere even when using a bolt with an assembled washer. | This type is equipped with a dustproof cover. Dust does not accumulate inside, making it hygienic. |
