This version has a \u003cb\u003eslotted borehole\u003c\/b\u003e rather than a round one, and that slot is the reason to choose it.\u003c\/p\u003e\n\u003cp class=\"crx-lede\"\u003eRafters sit where the roof was built, not where the array wants them. The slot lets the hook shift sideways on the fixing, so the rail line is set by the layout rather than by whatever centres the carpenter used.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eWhy a slotted hole\u003c\/h3\u003e\n\u003cp\u003eWith a round hole the hook lands where the rafter is, and any mismatch is taken up by moving the whole row. With a slot each hook is adjusted independently, which keeps the rail straight across an irregular roof and avoids the compromise of fixing into a batten because the rafter was 30 mm out.\u003c\/p\u003e\n\u003cp\u003eIt is a small part that saves disproportionate time on an old roof, where rafter centres are rarely as consistent as a drawing assumes.\u003c\/p\u003e\n\n\u003ch3 class=\"crx-h\"\u003eOrder alongside\u003c\/h3\u003e\n\u003cul class=\"crx-need\"\u003e\n  \u003cli\u003e\n\u003ca href=\"\/products\/k2-2003145\"\u003eK2 Climber 36\/50 Set\u003c\/a\u003e\n      \u003cp\u003eThe complete Climber set, where the standard round-hole version suits the roof.\u003c\/p\u003e\n\u003c\/li\u003e\n  \u003cli\u003e\n\u003ca href=\"\/products\/k2-2003527\"\u003eK2 Self-Drilling Screw 6.8x140mm\u003c\/a\u003e\n      \u003cp\u003eThe long fixing for getting through a battened build-up into the rafter.\u003c\/p\u003e\n\u003c\/li\u003e\n  \u003cli\u003e\n\u003ca href=\"\/products\/k2-2003221\"\u003eK2 SingleRail 36 Mounting Rail, 3.30m\u003c\/a\u003e\n      \u003cp\u003eOne of the two rail profiles this hook is made for.\u003c\/p\u003e\n\u003c\/li\u003e\n  \u003cli\u003e\n\u003ca href=\"\/products\/k2-2002332\"\u003eK2 NSP Height Compensator 4mm\u003c\/a\u003e\n      \u003cp\u003eTakes up small height differences between hooks so the rail sits true.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 class=\"crx-h\"\u003eQuestions on the Climber 36\/50\u003c\/h3\u003e\n\u003cdiv class=\"crx-qa\"\u003e\n  \u003cdiv\u003e\n\u003cb\u003eWhat do 36 and 50 refer to?\u003c\/b\u003e\n    \u003cp\u003eThe K2 rail profile heights in millimetres.
