Buy a 114mm Square Gutter Stop end at EasyMerchant
These square gutter stop ends are to cap off the guttering run at each or one end as most guttering systems have the running outlet at one end so it can be practical to use a stop end outlet on the lowest end, from the predefined fall, with the opposite end capped off with a stop end.
The external version of the stop end contains a rubber seal and can be just pushed onto the gutter length with ease creating a watertight seal.
