THIS LISTING IS FOR THE BARE WOOD — FULLY ASSEMBLED– VERSION OF THE POPULAR 8 FRAME SLATTED RACK. (not 10 frame Langstroth). EASY INSTALLATION: Place on beehives between the bottom entrance board and the lowest brood box and let them do the work. What is a slatted rack you may ask.. This is an exciting product that is sure to improve your beekeeping experiences. It has proven performance that is incredible for a device that is so affordable and simple to use! The difference by comparison in using one of these next to a hive identically set up but without it is almost silly. This hive accessory is now a must for each of my hives. I have reduced swarming in my apiary by an average of about 35% for several years now just by placing one of these between the lower hive body and the bottom. That alone saved me a fortune in lost honey production and time chasing swarms. Yes, even the managed hives can catch you off guard if you missed the swarm signs (which happens to all of us). Besides reducing swarming, These racks help build a MUCH stronger colony to take advantage of that nectar flow and also help keep the hive cool during the hot spells. “Bearding” on the hive entrance is all but eliminated!!! The bees can remain busy processing honey instead of hanging in a ball on their front porch. I cannot think of another device that improves the health and production of a colony of bees as easily as this does. The average increase in honey production per hive would pay for this item several times over in the first season (providing mother nature gave you a decent nectar flow) and it last for years and years!!! No gimmicks, snake oil, smoke and mirrors, or bogus claims. Just plain quality peformance! This Accessory works for the positive in so many ways. Its sure to help compliment all of your hard work providing the Very Best for your bees. These Slatted Racks work by drastically reducing congestion on the lower brood chamber allowing far less restricted brood rearing by the queen. Remember: A congested brood chamber is an EXTREME factor in swarming impulses. The front section is designed to reduce wind chill which will allow the queen to expand the brood pattern all the way down to the corners. This will increase brood output to its maximum potential during hive expansion for the nectar flows. The linear strips are mandatory for how this works and also allow bulk bees to hang under during cool spells and nights without crowding the queens laying progress. The design and spacing is etremely important and prevents the bees from continuing comb production below the bars. The depth is set to reduce bottom hung queen cells (which are harder to place in a breeder nuc) should your hive commit to swarm cells and you wish save them. This design will compliment a screened bottom with the slats aligning to a ten frame Langstroth style hive (which will allow mites to fall thru and perish). However this rack is still just as effective in swarm reduction and production increase with a solid bottom or 9 frame placement. The racks are constructed with all lap or dado joints to increase strength and the frames are assembled with LIFETIME STAINLESS STEEL crown staples to reduce splitting by (capturing wood grain) and Premium type 4 waterproof (FDA Approved) adhesive. I have these placed with confidence under my largest hives which can get well over 500 lbs each during nectar flow as did many hives this season! These racks are built with pride in the USA using 100% western red cedar (clear- no knots) from the Pacific Northwest. These may be used with other types of wood hives equally. The racks are manufactured with a higher level of construction and joinery by a very experienced shop. Why chance an unassembled kit when you can have a premium cedar rack, inspected for quality and assembled with STAINLESS STEEL staples. Note: racks listed here are unfinished bare wood (no paint or varnish). Product may be coated with a quality exterior (latex preffered) paint or varnish or left bare wood for a natural weathered look. 19 7/8 inched deep. (fits standard 8 frame langstroth style hive) I can assemble custom widths rapidly if you use narrower hives like 13 1/2 or? You can place the racks on hives anytime except during winter cluster periods. They benefit all 4 seasons once installed. Make sure you have your extra hive components on hand and ready. Are you ready for your next swarm catch or hive split? Also supplies can dwindle due to high demand and manufacturing can become overwhelmed during the spring rush so to avoid any possible delays get your items coming today. THE BEES DONT WAIT! Many customers combine these racks wih my Premium Screened Bottom Board for an unmatchable combination. Thank you for looking and Please feel free to ask any questions.
