Best Lockout/Crank Stringing Machines

Manual Crank stringing machines are the perfect middle ground between wanting a professional, sturdy, and tension-accurate machine without breaking the bank.

For amateurs, businesses, or even professionals, manual crank machines can often prove to be the safer and better option as they offer a more hands-on and involved procedure to stringing that doesn’t feel automated like with electric stringing machines or non-technical with drop weight stringers.

In essence, electric stringing machines and crank machines are identical in their mode of application to produce and retain tension in the string. The string is inserted into the device often called the jaw. Then by simply turning the crank, the string is wound and pulled, creating tension.

Unlike in drop weight stringers and some electric machines, there is no constant pull in the string as upon reaching the desired tension, the string is uncoupled and held in place by brakes to maintain the tension.

Now with all that said and done, let’s finally get into our selection of the top 5 crank stringing machines.

Crank Stringing Machines Knowledge

Now with the knowledge of how crank/ lockout stringers function, let’s discuss the main criteria for finding the machine best for you. Luckily, most crank machines are similar to each other and have few if many variations but at the same time, it’s these tiny, useful, and quality-of-life features that best distinguish one machine from another.

The main criteria boil down to budget and application. The budget is self-explanatory and except for 1 stringer, all the machines mentioned below are only $200 to $300 apart at max.

It is also important to know about some important common features of a crank machine and their greater implication on the use of the use. Knowing what to look for can help expedite the decision-making process. The following are some factors to consider:

Clamp System

The clamps are the instruments that hold the string in place during and after applying tension. 2 types of clamps are present on stringers: fixed and floating clamps.

Floating clamps

These clamps aren’t connected to the machine and hang from the string they are attached to. Cheaper and less technical machines designed for amateurs feature floating clamps as they are more user-friendly but offer little in the way of retaining accurate tension in the string. As a rule of thumb, first-time stringers should look for a machine with floating clamps as they are not restrictive and changing their location mid-stringing is much easier, while professional or commercial stringers should avoid these claps due to the inconsistent tension results these floating clamps provide.

Fixed clamps

As the name suggests, fixed clamps are directly attached to the machine body, at the turntable that houses the racquet. These clamps themselves come in 2 varieties, non-swivel and swivel clamps. Non-swivel clamps are what you might think of when you hear fixed clamps as they don’t offer much versatility and can only move along a single plane the bar they stand on allows. Swivel clamps on the other hand are much more technical and can glide across the system, and can be apply in most locations due to their ability to rotate the clamps around a pivot. They are the preferred professional option with the best capacity for accurately retained and consistent pressure in the string. Naturally, they cost the most as well.

Mounting System

Mounting refers to docking your racquet into the machine and it is the first step in the stringing process. Tennis stringers can either have 2, 4, 5, or 6-point mounting systems with each point referring to the number of machine contacts that hold the racquet. A 2-point mounting system will hold the racquet in 2 places, at the head and the throat, a 4-point mounting system will hold the racquet in 4 locations, and so on. Many stringers prefer the lower point mounting systems of 2 or 4 as stringing can be easier and faster. There is less room for string entanglement and fewer stringing openings will be obstructed by the clamps holding the racquet itself. It is important to note however that the racquet will stretch and deform during the stringing process. More point systems offer robust structurally sound protection from the bending so there is minimal damage to the racquet frame. It ultimately comes down to preference and the same is the case for clamps but it is generally understood that 5 and 6-point mounting systems are superior. The price will go up as the point system does as well.

Table-Top or Standalone

Table-top machines have no long stand or base and are great for users that will be moving their machines. They can easily fit in a car and are lightweight when compared to standalone devices. All you need is a good and sturdy flat surface to begin your work on and you are set to start stringing.

Thus, novice players and those looking to string at home are better off with Table-top stringing machines. The standalone/ upstanding stringing machines are not as easily transportable. They require you to be standing but most come with adjustable heights.

The machine is generally much sturdier and the up-right position allows for faster stringing. Businesses or stringing pros prefer the standalone models. They cost more but most come with extra features like a tray for holding tools or a compartment for string.
