Frames drift. If you've opened a box and found the frames compressed to one side or unequally spaced, you know the problem. Metal frame spacers fix it at the box level — two spacers install into the top ledge of the box (one per side), and every frame hangs from the spacer rather than sitting freely against wood. Each frame slot is fixed. You pull frames from known positions, replace them in known positions, and the colony never has to re-establish consistent spacing after an inspection. The FBC spacers are designed without gaps between frame slots, which means small hive beetles can't use the spacer itself as a hiding spot — a common flaw in other designs where the beetle can tuck into the space between the frame lug and the spacer housing. Height is also adjustable: slide the spacer up or down in the ledge groove during installation to control how much of the spacer sits above the frame rest. A small adjustment at setup gives you the fit you want for your specific frames. Most beekeepers run 10-frame spacing in brood boxes and switch to 9-frame spacing in honey supers. Wider spacing in supers allows bees to draw thicker comb — which is easier to uncap and holds more honey per frame. If you're setting up honey supers, see the Metal 9-Frame Spacers instead. Key Features Equal 10-frame spacing — every frame hangs at a fixed position. No sliding or bunching. No beetle gaps — spacer design eliminates the hiding spots that other designs create at the frame lug interface. Adjustable height — slide up or down in the ledge groove during installation. Set once, leave permanently. Steel construction — durable, won't warp, won't compress under the weight of frames over time. Two per box — one spacer installs into each side of the top ledge. Sold individually or as a 20-pack (enough for 10 boxes).
