The full depth of a V-section T-Link Belt is made up from 3 overlapping sections. 
The belt is joined or broken by simply rotating the T-headed pins until they line up with the slots cut in a each link. 
Although the pins go right through each link there is always clearance for them in the bottom of the V pulley 
Commonly known as "Link Belts", which is a type of V-belt (it cannot be used on flat-belt drives), is widely used in industrial and marine applications. Although more expensive than ordinary V-belts it does have some important advantages.
