New snap on boxes are shit!!!!!!i bought a brand new 53" roll cab around 2001,had it In the workshop then in the back of the van where it took a lot of hammer,going on building sites off road ect never had any problems. Then last year a bought a rand new 40" roll cab and it's crap!!!with in the first few weeks the roller bearing runners had dropped to bits and then the lock fell to bits as well. I still have the older box and when you compare them next to each other the older box looks better made and feels a lot stronger. I've all ways bought snap on tools but I will never buy another box.
