KastKing Tabletop Line Spooler

From the Amazon Listing

• SPOOLS SPINNING & BAITCASTING REELS WITH NO LINE TWIST – KastKing TrueWind fishing line spooler routes fishing line from the filler spool to your reel in the correct direction for spinning reels and baitcasting reels, helping reduce line twist, wind knots, loops, and uneven line lay when loading braid, monofilament, or fluorocarbon.
• CLAMP-ON LINE SPOOLER FOR RODS OR TABLETOPS – Versatile clamp opens up to 1.75 in so you can mount to a fishing rod blank for spooling, or clamp to a table, desk, or countertop at home. Rubber-coated clamp pads help protect rods and surfaces.
• CONSISTENT TENSION FOR TIGHT, EVEN LINE LAY – Use the tension band to keep steady pressure on the filler spool so line wraps smoothly, evenly, and tight on your reel spool. Helps prevent loose wraps, digging-in, and uneven spooling with braid, monofilament, or fluorocarbon.
• FITS MOST FILLER SPOOLS + EASY SETUP CUES – Threaded T-handle secures common filler spools up to 3.5 inches wide x 4.5 inches in diameter. Built-in instruction cues act as a quick reference to help you set up correctly for spinning reels vs baitcasting reels.
• TOUGH, IMPACT-RESISTANT BUILD + LINE CUTTER – Molded with durable amorphous polymer for resistance to heat and chemicals. Key components use strong, tough thermoplastic materials for long-lasting performance. Integrated cutting cartridge on the T-handle makes it easy to cut line cleanly after spooling.
