Claw Machine

Claw Machine is a Switchback opener created by HDChung, and also contributed by Winterfrost and cat. This opener is notable that it can be continued to T-Spin Triple tower relatively reliably.

Second Bag
Note that you only need to fill the first row of the left side for a T-Spin Double.

It is also possible to stack like these, but no continuation has been researched yet.

Third bag
One can always possible to stack like this if 180° spin is enabled.

Alternatively, those two continuations are also considerable but the second one would not have 7-2 stacking continuation while it can be always stacked.

Triple T-Spin Tower
The left side can be filled in freestyle. These are some examples.

7-2 Stacking
early T bag can continue this opener into 7-2 stacking. The following example shows conversion into LST stacking.

5-bag Perfect Clear
With 180° spin, it is possible to stack like this most of the time.

In SRS+ (Tetr.io), note that this 180° L spin is possible.

This will lead to a 100% Perfect Clear field with 9 minimal solutions, all of which are shown below.

These are the solutions which might lead to potential T-Spin/Tetris.

Lasso Triple T-Spin
While having some dependencies, this continuation will lead to a flat residue. After building an overhang and performing a T-Spin Triple, use S or Z for another overhang for the lower T-Spin Triple. S overhang, Z overhang, and T overhang are possible, but they are not recommended.
