Carlos Diaz, a spokesman for Customs and Border Protection, said the agency is still in “the testing phase” and that results are being evaluated. Only once did a tester manage to land a hook on top of the wall without help, the official said. Tubes atop some models repelled climbing devices but wouldn’t work in more mountainous areas because the terrain is too jagged. A proposal by Customs and Border Protection calls for spending $18 billion over 10 years to extend barriers to cover nearly half the border, though it is unclear if Trump supports that plan. ELTA North America Inc., part of state-run Israel Aerospace Industries, and KWR Construction Inc. of Sierra Vista, Arizona, built models from other materials.
