We have made a specification change to the rear cover of the caulking gun with the strong-type handle.
After the change, the depth of the rear cover has become shallower, so that the threads of the main body can be seen when the gun is installed.
Even if the threads are visible, the gun is still tightened properly and there is no problem with the product performance. Please be assured that this is a design specification and not a defective product.
We hope you will continue to patronize our products.
