Running 9 frames instead of 10 in a standard box gives bees room to draw thicker comb — easier to uncap at harvest and holding more honey per frame. These metal spacers install into the top ledge of the box and space 9 frames evenly across a 10-frame box, so every frame hangs at a fixed position instead of drifting or bunching. Key Features Evenly spaces 9 frames across a standard 10-frame box Encourages thicker comb — more honey storage per frame Thicker comb also makes uncapping and extraction faster Adjustable height — slide up or down in the ledge groove during installation No extra gaps for small hive beetles to hide in, unlike some spacer designs Durable steel construction for long-term use in supers or brood boxes Best Used With Drawn Comb These spacers work best on frames that already have drawn comb — bees extend the existing comb outward to fill the wider spacing. Used with brand-new foundation instead, bees may build cross comb, which makes frame management harder. If you're setting up new foundation, standard 10-frame spacing is the safer starting point.
