The 618 space saver made from a hard transparent plastic with ridged sides on all four corners helps with keeping the lid in a semi locked position so when using longer staples you can adjust depth of the container, the larger version of the space saver compared to the 617, will hold a whole box of Tacwise 8mm or 10mm’s staples still in its box or can be used for Spotnails staples such as the 606 18mm/22mm & ME 4000 staples Etc.
