Product description: The car repair gecko does not have high requirements for the depth and cleanliness of the concrete cavity. It is easy to install and inexpensive. Choose the appropriate embedding depth according to the thickness of the solid roof. As the embedding depth increases, the tensile force increases, and this product has a reliable expansion function. Body material: stainless steel, carbon steel and other metal materials.

Product characteristics: This product has a longer thread and is easier to install, and is usually used in heavy-duty facilities. To obtain a reliable, huge fastening force, it is necessary to ensure that the clamp ring fixed on the gecko is fully expanded. And the expansion clamp ring must not fall off the rod or be twisted in the hole. The calibrated tensile values ​​are all tested under the condition of cement strength of 260~300kgs/cm2, and the maximum safe load shall not exceed 25% of the calibrated value.

Application areas: suitable for concrete and dense natural stone, metal structures, metal profiles, bottom plates, support plates, brackets, railings, windows, curtain walls, machines, girders, stringers, brackets, etc.
