Clamps Securely While Allowing For Various Mounting Options

The AIA-CF and AIA-J adjustable insulator adapters clamp securely to a tie-top insulator by tightening the take-up handles. Natural rubber cushions permanently molded to the adapter protect the porcelain and restrict the adapter from rotation. The XS-100-B block can be mounted in the adapter vertically and at various angles to facilitate stringing tangents and angles.

Using the AIA adapters and XS-100-B, reconductoring is possible using the “Never-An-Outage-System,” as the conductor can be energized while in the block. These adjustable insulator adapters and XS-100-B block combination can also be used for conventional stringing on crossarms, on new construction, and on vertical or horizontal post insulators.

For larger than 4 7/8″ or smaller than 2 1/8″ neck diameter insulators, other adapters are available on request. Also available is Model No. AIA-4 Special with 3/4″ hex head (instead of standard hand knob) ideal for use with hydraulic tools.

Key Features


Used for reconductoring on vertical tie-top post insulators.


Permanently molded natural rubber cushions protect the porcelain and restrict  adapter rotation.


Fits all Sherman+Reilly XS-100-B stringing blocks. AIA-CF adjusts to fit most insulators with neck diameter for 2-1/8 in. through 3-1/2 in. The AIA-J adjusts to fit most insulators with neck diameter for 3-1/4 in. through 4-7/8 in.


2 models available: AIA-CF, and AIA-J.
