The #153 "Scale" All-Metal Self-Centering "WHISKER"® Coupler features a "Scale" Metal Coupler (a smaller-head coupler which is more to scale and is patterned after the type 'E" couplers) & Metal "WHISKER"® Centering Spring, insulated Draft-Gear Box and Lid.

The #153 Coupler may be mounted with the supplied #242 draft-gear box or with the manufactures cast-on coupler pockets. The coupler will couple and uncouple with other Kadee® HO and HOn3 couplers. The coupler has the same shank length as the #23 or 43 coupler which will allow the modeler to remove the existing #23 or 43 coupler and replace with the new smaller coupler. The #153 coupler is made of the same metal as the #43 for strength and rigidity.

It is not recommended to use a metal coupler directly on a metal surface or in a metal draft-gear box to avoid the possible electrical crossover or shorting that may cause damage. Use the provided insulated draft gear box.

The #153 package contains two pair of the new coupler, two pair of the #242 draft-gear boxes, and instructions.
