Costco Ladder
If you're looking for the Costco ladder, that can mean one of several things. Obviously, it indicates that you're looking for a versatile, convertible ladder. There's the ClimbTek Ladder available from Costco. There's also a Cosco ladder company that makes a convertible ladder. Or perhaps you've seen a demonstration of the original Little Giant Ladder System at your local Costco. No matter which brand you're looking for, you have a decision to make and you deserve to know everything about these brands before you buy.
ClimbTek
The articulated ladder from Costco is the ClimbTek Ladder. ClimbTek offers two models of articulated ladders: one with one hinge and one with three hinges. While three hinges enable the ClimbTek to finagle itself into different positions, few of these positions are fully safe for use and multiple hinges introduce more instability. Only one end of the ClimbTek features a support bar-ladders need stabilizing at both ends. Finally, the ClimbTek doesn't telescope to different heights like many other convertible ladders do. Clearly, the ClimbTek is not the most versatile choice.
Cosco (Costco Ladder)
The Cosco Ladder (sometimes inadvertently spelled 'Costco ladder') is another convertible, articulated ladder. Unlike the ClimbTek, both ends of the Cosco Ladder are flared for increased stability. The Cosco Ladder also telescopes for increased versatility. But money saving construction in the hinge and rung attachment of the Cosco Ladder significantly reduce its sturdiness and strength, especially over years of use. For this reason, we believe the Cosco Ladder is not the safest convertible ladder available.
Little Giant
The Little Giant Ladder System has everything that any other Costco ladder lacks. With one secure, patented, locking hinge, the Little Giant folds and telescopes into any position you might need. With both ends flared for maximum stability, the Little Giant won't rock or tilt. Its double zigzag welds keep the rungs securely attached no matter what you might subject your ladder to.
