Large and Small Yellow Regulator Plates

Product Overview

The SL-125 regulator plate set gives farms two slotted yellow plastic plates for adjusting winch height positions. The small plate is 2 cm wide and 5.8 cm tall, weighing 4 g, while the large plate is 3.5 cm wide and weighs 12 g. Both carry holes and a diagonal slot that let the winch cable or bracket slide to the desired position before being locked.

These plates are used wherever the lifting or ventilation winch in a poultry house needs stepped height adjustment. The slotted design means the bracket can move along the plate to set the drinker line height for different bird ages, then be fixed with a bolt through one of the holes. The two sizes cover small winch brackets and larger ones used on heavier lines.

Key Features and Benefits

• Two plate sizes - small 4 g plate and large 12 g plate for different winch bracket loads.
• Slotted adjustment - the diagonal slot lets the bracket slide to fine positions before locking with a bolt.
• Multiple hole positions - round holes give fixed step heights along the plate.
• Yellow color coding - easy to spot during winch adjustment walks around the house.
• Light plastic plates - add almost no weight to the winch hardware they adjust.
• Reusable - plates stay intact through many height adjustments over the flock cycle.

Materials and Quality

Both plates press from a yellow resin blend stiff enough to hold the stepped height positions against the winch pull. The hole edges and slot walls are formed to take a bolt without tearing, so the plate holds the chosen height position steadily. Every plate is inspected for clean holes and even edges before cartoning.

The yellow color is molded into the plastic, so the plates stay visible even when covered in dust. We keep both sizes produced to the same hole spacing logic, so a farm can mix small and large plates on adjacent winches without re-drilling.

The diagonal slot is cut at a shallow angle so the fitting climbs the slot as the line rises, and the round holes are chamfered so the bolt seats without wobble. The yellow plastic is stiff enough that the slot edge does not widen under the repeated pull of the winch.

How to Use and Maintain

Bolt the plate to the winch bracket, slide the cable or fitting along the diagonal slot to the desired height, then lock with a bolt through the nearest round hole. Adjust the drinker line height step by step as the birds grow, moving the fitting to the next hole at each stage.

At each line-lowering stage, glance at the slot edges for hairline cracks, and tighten the fixing bolt if the plate shifts when you nudge it. Keep a few spare plates on the farm so a cracked regulator can be replaced without interrupting the daily height adjustment routine.

Slip the winch fitting into the slot, slide it to the next hole each week as the birds grow, and drop the fixing bolt through the aligned hole. Record the current hole number on the row board so every crew member lifts the line to the same height.

Applications

Winch lifting systems on grow-out houses use these plates to step the drinker line up as the birds grow. The small plate suits light lines and the large plate suits heavier runs with more fittings per meter.

They also suit curtain ventilation winches that need stepped opening positions, because the slotted design works for any cable-guided adjustment. Distributors stock both sizes together so a service truck can adjust light and heavy winches in the same house visit.

Broiler integrators use the stepped holes to set drinker height for each growth stage, while layer farms use the slot for fine daily tweaks. Both plates are also used on curtain winches that need the same stepped opening positions through the summer.

Frequently Asked Questions

Q1: What is the slot used for?

The diagonal slot lets the winch fitting slide to a fine height position, while the round holes lock the step positions.

Q2: Which size fits my winch?

The small 4 g plate suits light brackets, and the 12 g large plate suits heavier winches; tell us your bracket size if unsure.

Q3: Can the holes be re-drilled on farm?

We recommend using the molded holes as supplied, since re-drilling can weaken the plastic plate under load.

Q4: What if a hole wall cracks?

Replace the plate, because a cracked hole no longer holds the bolt at the chosen height position. If you are fitting the plates to an older winch, bring a photo of the bracket; we can confirm whether the molded holes line up with your existing bolt. The small plate suits light winch brackets and the large plate suits heavier ones, so one order covers both. If you are replacing plates on an older winch, measure the old plate slot spacing first and we will confirm the match.
