I hope so! I purchased one very similar to the ECONTRIC model in this post, from Titan Fitness. It arrives on the truck on Wednesday with more home gym equipment so I can resume my training.
Since these pull-up bars are about 32" deep and I will use 2x4 for stringers so about 33-34" total. My plan is to do my vertical pulling (bodyweight + 100lbs) and horizontal pulling (Adv Tuck FL Rows +65lbs) so it must be very stable and secure. These pull-up bars are rated up to 500lbs! Today I purchased six 3/8 lag screws 6" long to attach it to wall studs. That should be very strong!
