Before choosing the Pullrite, I researched the forum and other sources. Both Pullrite and B&W seemed highly recommended though the Pullrite appeared more popular. I wanted to use my existing rails and the B&W doesn't show anything beyond 18K. Still I have to say I was surprised and think it a poor design that I can't close it with a handle or, at the very least, a factory supplied tool. Leaving it to customers to determine what is a safe and suitable "probe" is asking for trouble.
